Part 1: Freezing of biological samples, is it really best?
When freezing is best
Freezing of biological samples is a priori considered the best way to preserve all biological samples but is it really? This belief may stem from the fact that the only practical way to preserve solid tissue samples is by rapid freezing and long term storage at -80°C or in liquid nitrogen. Freezing is the best way to preserve tissue samples because chemical preservatives cannot penetrate deeply and quickly enough to stop all biological activity before degradation starts. This may have led to the belief that freezing is also the first and best choice for preserving all other biological samples such as purified DNA. Once a biological sample has been carefully removed from the sample and purified it becomes readily accessible to using active chemical preservation to provide a much more reliable form of preservation for long term stable storage without the need for refrigeration at -20°C to -80°C.
Freezing is only passive protection
Freezing for long term storage of purified samples provides protection by slowing down all chemically generated attacks. The common modes of chemical degradation of DNA in storage are oxidation and hydrolysis which will cause breaks in the DNA strands over time. In general, for each 10°C that the temperature is lowered there is a halving of the rate of all chemical reactions. So dropping the temperature 20°C from room temperature would reduce the undesirable effects of oxidation and hydrolysis by a factor of four. The slowing of the reaction rates is the only protection provided by freezing a sample.
From liquid to frozen and back again
Freezing a biological sample is not as simple and error proof as may be assumed. During freezing of a water based sample a wave front is generated as the crystal interface moves through the liquid. This interface can cause significant local shifts in concentration and cause mechanical stresses on large molecules such as DNA, RNA and proteins as it passes through the solution. How this wave front is generated is driven by how fast or slow the freezing takes place. Slowly dropping the temperature will generate larger crystals and large wave fronts while rapid freezing, plunging the sample into liquid nitrogen for example, will generate many small crystals. And of course the reverse will happen as the sample is thawed. The need to control the potentially harmful effects of freeze and thaw cycles is well documented for protein solutions1 and may be an issue for the more labile RNA samples.
Active chemical protection
GenTegra uses a different approach, active chemical protection, by providing a specific chemical matrix that is designed to provide active protection for purified samples. Our GenTegra-DNA matrix is an active chemical protection designed to sacrifice itself to protect the DNA sample. In addition to the direct chemical protection when added to the DNA solution, once the DNA and GenTegra-DNA matrix is dried an additional protective barrier is formed around the DNA by the matrix.
Part 2
Active Chemical Protection or freezing?
GenTegra uses a different approach to preserving and protecting DNA, active chemical protection designed to protect against the expected modes of damage. The common modes of chemical degradation on DNA are oxidation and hydrolysis, both of which cause breaks in the DNA strands over time. GenTegra-DNA uses active chemical protection by providing a targeted chemical matrix that is designed to provide active protection against oxidation and hydrolysis. With the DNA removed from the original tissue or cells it is directly exposed to external chemical attack and also amenable to direct active chemical protection. The GenTegra-DNA matrix is made up of specific chemicals that are designed to react first with the reactive chemical species that are likely to damage the DNA.
Immediate and long term protection
Active chemical protection is provided immediately in the initial liquid form when GenTegra-DNA is added to the purified DNA solution or the DNA is added to the sample tube containing the GenTegra-DNA. However, the level of protection increases dramatically when the DNA solution and GenTegra-DNA are dried. As the solution is dried, the GenTegra-DNA concentrates around the DNA and forms a plastic-like layer surrounding the DNA that is present. This layer not only provides the protective barrier but puts the anti-oxidation and anti-hydrolysis matrix in an extremely high concentration compared to both the DNA and the active species that might damage the DNA. The presence of this cocoon like barrier around the DNA provides a physical protective barrier in addition to the active chemical protection layer protecting against oxidation and hydrolysis attack.
Failure immune storage and shipping
Once DNA is dried in the GenTegra matrix it is actively protected against the common modes of degradation and is essentially impervious to many concerns that remain if samples are frozen. Storage of DNA on GenTegra-DNA is at ambient temperatures so power outages, freezer breakdown or forgetting to put the sample back in the freezer at not going to damage the DNA. The term ambient temperature actually includes temperature ranges from below zero, °C or °F and as high as 56°C for prolonged times providing safe storage almost anywhere in the world without providing heating or cooling. This makes GenTegra matrix ideal for shipping purified samples from remote locations to a central laboratory for analysis, no ice packs or dry ice are required and shipping delays will not adversely affect the samples. About the only things GenTegra-DNA does not protect against is fire and actual physical damage to the tubes containing the DNA.
To use, add water and go
After storage or shipping of a sample protected by GenTegra-DNA the sample is reconstituted by adding molecular biology grade water to the sample. The matrix of DNA and GenTegra dissolve quickly and is ready for immediate use in all downstream analysis without the need for any intermediate purification step, just dissolve and go.
To summarize, GenTegra-DNA uses active chemical protection to protect DNA from hydrolysis and oxidation at a wide range of ambient. This dry stabilization technique protects while shipping at ambient temperatures without ice or cold packs, To use stored samples, simply add back water, mix and aliquot a sample, then dry the remaining sample and return to storage.

Part 3
Active Chemical Protection and RNA?
In Part 1 of this tutorial series we discussed freezing as the acknowledged standard for preserving tissue samples, but challenged freezing as the best way to store purified DNA samples when compared to active chemical protection using GenTegra-DNA in Part 2. In this tutorial, Part 3 of our series, we discuss active chemical protection as it is applied to the special needs of purified RNA.
Active chemical protection, different but the same
GenTegra-RNA is designed to provide the same level of ambient temperature protection for RNA as GenTegra-DNA provides to DNA. The two products start much the same but GenTegra-RNA is then enhanced to provide the additional protection that is required by RNA to keep it stable. RNA is much more labile and subject to forms of degradation that are just not much of a worry when dealing with DNA, particularly from RNases that are pervasive in the environment. DNases do not represent the same level of threat when working with purified DNA.
Immediate and long term protection
GenTegra-RNA starts with the same chemicals that provide the same ambient temperature protection as GenTegra-DNA against hydrolysis and oxidation, but adds a potent RNase inhibitor. This powerful RNase inhibitor provides protection immediately in the liquid state. When a sample is dried in GenTegra-RNA the RNase inhibitor remains present and active but the RNase enzymes are inactivated in the dry state. Later, when the RNA sample is rehydrated for analysis, after shipping or for retesting after a period of storage, the RNase inhibition becomes active again protecting the RNA against any trace of RNase activity that may still be present.
Similar where it counts
Although the formulations are significantly different between GenTegra-DNA and GenTegra-RNA they both share the common advantage that neither cause any interference in the downstream analysis. No further purification is required for any of the common genomic analyses: PCR, qPCR, Sanger sequencing or NGS. With most current analytical techniques requiring far less than the isolated sample, both GenTegra-DNA and GenTegra-RNA also share the ability to be dried and rehydrated 5 times without loss of protection, allowing aliquots to be easily taken and the residual dried down for further ambient temperature storage.
To summarize, GenTegra-DNA and GenTegra-RNA use active chemical protection to protect against hydrolysis and oxidation at a wide range of ambient temperatures and GenTegra-RNA adds additional protection against any RNase activity that is present. Active chemical protection while shipping at ambient temperatures eliminates the need ice or cold packs and the expense of expedited overnight shipping. To use RNA samples dried on GenTegra-RNA, simply add back water, mix and remove an aliquot, then dry the remaining sample and return it to storage.
Part 4
Introduction
GenTegra®-DNA and GenTegra®-RNA can be used to protect DNA and RNA samples from 1uL to 20 µL of sample volume. In Part 1 of this tutorial series we discussed freezing as the acknowledged standard for preserving tissue samples, while in Part 2 and 3 we discussed using active chemical protection as a superior storage method for purified DNA and RNA samples. In this, part 4 of our tutorial series we will discuss special issues surrounding samples of less than 20 µl.
Active chemical protection, what’s in the tube?
When tubes of GenTegra®-DNA and GenTegra®-RNA are manufactured each tube contains 21 µl of GenTegra matrix. This 21 µl is carefully added to the tube so that the volume of GenTegra matrix is placed at the bottom of the tube. Immediately after adding the 21 µl of GenTegra solution the tubes are dried. As the solution dries it leaves behind a residual layer of GenTegra matrix on the walls of the tube at a height equal to the original 21 µl. This is why we recommend a minimum sample volume of 20 µl be added to the tubes in normal use. A 20 µl sample volume ensures the sample dissolves all the GenTegra matrix on the sides of the tube. For samples smaller than 20 µl special care and consideration must be used.
Immediate and long term protection
GenTegra-RNA starts with the same chemicals that provide the same ambient temperature protection as GenTegra-DNA against hydrolysis and oxidation, but adds a potent RNase inhibitor. This powerful RNase inhibitor provides protection immediately in the liquid state. When a sample is dried in GenTegra-RNA the RNase inhibitor remains present and active but the RNase enzymes are inactivated in the dry state. Later, when the RNA sample is rehydrated for analysis, after shipping or for retesting after a period of storage, the RNase inhibition becomes active again protecting the RNA against any trace of RNase activity that may still be present.
Working with sample volumes less than 20uL
Working with sample volumes between 10 µl and 20 µl is relatively straight forward. Once the sample has been added carefully to the bottom of the tube it is mixed with the pipette by several in and out actions. For these small volumes do not vortex the sample, it is too easy to lose sample on the sides of the tube and the sample volume is too small to be unaffected by the wetting it will leave behind on the side walls. If the sample is high on the side walls after mixing it is almost impossible to ensure you can recover it at a later date even if a larger recovery volume is used. A brief centrifugation can help ensure the sample and matrix are in the bottom of the tube before drying. For volumes of 10-20 µl, we recommend rehydration in 20 µl to ensure recovery of all the sample. For volumes smaller than 20 µl, withdraw the sample more slowly to allow maximum flow of sample into the pipette tip and ensure maximum recovery.
Most tubes used in the laboratory today are low binding but if the sample is placed in the tube above the GenTegra coated portion at the bottom some binding may occur. The GenTegra matrix generally prevents binding of DNA or RNA to the walls of the tube but may not counteract binding of the sample to the tube wall if sample is already dried and as a consequence binding has already occurred. To prevent the possibility of binding to the sides of the tube, extra caution needs to be taken to carefully place the sample at the bottom of the tube where the GenTegra matrix coats the sides of the tube.
Working with sample volumes less than 10uL
Sample volumes of 10 µl or less pose a special challenge, not in protecting the sample but in recovering the sample later. Samples of less than 10 µl are easily protected because of the presence of an excess of the protective matrix. Even when small volumes are carefully placed into the bottom of a tube it is all too easy to deposit that small volume on the side of the tube rather than on the bottom. When the same small volume is used to recover the sample it may not be placed where the original sample was placed and therefore the sample will appear to be lost or reduced when in reality it is still in the tube. The recovery volume of water must come in contact with the dried DNA/RNA sample in order to recover the sample. Do not vortex, to mix volumes <10 µl, gentle re-pipetting is advised.
Summary
For sample volumes less than 20 µl we recommend recovering with a volume at least twice the original sample volume and preferably using 20 µl. For sample volumes <5 µl we recommend a recovery volume of at least 10 µl. Small samples will be well protected by GenTegra but if the sample is lost due to handling difficulties it is still lost, protected or not. If you can accept the dilution, using a recovery volume of 20 µl for all samples less than 20ul will reduce the risk of inadvertent sample loss due to simple pipetting errors.

Part 5: Active Chemical Protection in the Biobank: Saving space and reducing costs
Are you running short on space, or funding, or faced with creating a safe, secure means of backing up your DNA specimens?
GenTegra®-DNA can be used to protect DNA samples and avoid the ongoing expense of running and maintaining multiple freezers. In this, part 5 of our tutorial series we will discuss the ways ambient storage of DNA, using GenTegra-DNA, can save space while at also reducing operating costs.
What every biobank wants
There are three key issues that drive every biobank today: sample protection, controlling cost, and limited space. Whether the biobank operates a repository or an archive the efficient use of space is important. And eventually as the storage needs grow and more and more freezers are added, a lack of available space becomes a looming concern.
Space saving is about the sample container & freezer inefficiency
A quick measurement of any freezer will show that approximately 30% of the space it occupies is used for the refrigeration equipment and the insulation to maintain the temperature. This is 30% lost storage space when compared to an ambient storage method that does not require any power equipment or insulation. Simply treating samples with GenTegra-DNA and moving them out of the freezer allows you to store 30% more samples in the same space. And as no power is needed to protect the samples, power outages are no longer a concern for the samples stored dry on GenTegra-DNA.
When you look into a freezer used for storing biological samples it is often filled with cardboard boxes that hold either 100 small sample tubes or 81 slightly larger sample tubes. This format is often the de-facto format when sample preparation and purification are done manually. The tubes, though small, allow for labeling that identifies the samples. It is also a convenient format when it is necessary to withdraw a sample that has been requested for further study. This sample box format is, however, one of the more space inefficient formats. Maximum space efficiency is found by using the 96-tube rack format or by using standard 96 well microplates. When compared to the standard cardboard sample tube boxes these 96-tube racks are capable of storing nearly 3 times as many samples in the same space. And a standard 96 well microplate is even more as many samples in the same space. And a standard 96 well microplate is even more efficient, storing >5 times as many samples as a rack full of 100 tube cardboard boxes.
Reduced operating costs with ambient temperature storage
Efficient use of space saves money in obvious ways but how does one save money by moving samples from freezers to ambient storage when the preservation chemistry costs money? A recent publication1 by an ISBER study group looking at the costs of freezer storage found a reasonable low end cost for freezer storage to be $2.40 per sample over a 10-year period. A major US pharmaceutical company estimates their biobank costs at $1.00 per sample per year or $10.00 per sample for a 10-year period.
GenTegra offers a product especially designed for biobanks using automated DNA purification systems, GenTegra-DNA Bulk. This product is designed to easily fit into the automated purification process and to allow adding of the GenTegra-DNA immediately following the purification step. The samples are then dried and are ready for long term storage. This product provides GenTegra-DNA at a starting cost below $2.40 per sample. Biobanks with yearly sample rates of 5,000 or more will see per sample costs well below $2.00 per sample. Besides a lower 10-year cost for using ambient dry storage, ambient technology also offers safe and secure storage with freedom from concerns about power outages or power backup systems. Ambient dry storage on GenTegra-DNA has an acceptable range, not of an air-conditioned lab but from (-80°C to +72°C).
Space efficient, highly secure but costly
One biobank requirement where additional cost is justifiable is secure sample tracking. Many samples in the freezers are individually labeled by hand either with a Sharpie® or a freezer label. Both of these, to a lessor or greater degree, are subject to failure of the labeling system. This issue has been addressed with the 2D 96-tube rack labeling system that provides a permanent 2D barcode on each tube. This format is space efficient and incredibly secure in its labeling as the barcodes are an integral part of each tube. However, this format is an expensive format as the 2D barcode adds a cost of about $0.30 per tube and the use of a screw cap adds another $0.282. Cost drops with volume usage but it is still an expensive per sample cost for storage. These extra costs may be justifiable because of the security provided and the ease of interfacing to an electronic sample tracking systems that are also required for tracking samples in a large biobank.
An interesting side point is that manual labeling systems, hand written with a Sharpie or using an adhesive label are much more secure and less subject to failure when they are not stored in a freezer. Much of the extra expenses for labels are due to the need for the labeling to withstand freezer conditions and freeze thaw issues. None of these issues are of concern for samples stored at ambient temperatures.
If you need more capacity without increasing your biobank’s space requirements, consider adopting a more space efficient form of labware, and at the same time “Freezer proof” your samples with GenTegra-DNA to keep them safe, secure and immune to power failures or natural disasters. And these gains in space, economics and security can be made with minimum cost in time and budget, and maximum benefit to your biobank.
GenTegra’s Financial Conflict of Interest Policy
Financial Conflict of Interest Policy
GENTEGRA
Financial Conflict of Interest Policy
GenTegra, Inc. Financial Conflict of Interest Policy for Investigators and Subrecipients on Public Health Service (Including NIH) Grants, Contracts, and Cooperative Agreements
I. Purpose. This Policy has been established as of January 8, 2021 to comply with the requirements of 42 CFR Part 50 Subpart F federal regulations on the Responsibility of Applicants for Promoting Objectivity in Research for which PHS Funding is Sought and Responsible Prospective Contractors, commonly known as the Financial Conflict of Interest regulations (the “Regulations”). GenTegra shall update this Policy periodically as needed to comply with changes in the Regulations.
II. Applicability. This Policy applies to all Investigators and Subrecipients who participate in research funded by grants, contracts, and cooperative agreements with the Public Health Service (PHS), including the National Institutes of Health (NIH), and other research funded by a government contract that incorporates the Regulations in its terms (collectively, “Covered Research”). The term “Investigator” means an employee, consultant, collaborator, or agent of GenTegra who, regardless of title or position, is responsible for the design, conduct, or reporting of research proposed for funding, or actually funded, under Covered Research. The term “Subrecipient” means a grant subrecipient, subcontractor, or other person or entity who has responsibility for the design, conduct, or reporting of research proposed for funding, or actually funded, under GenTegra Covered Research. Unless special circumstances apply, vendors of supplies and equipment to GenTegra and vendors who provide routine testing services to GenTegra without any significant knowledge of the Covered Research are not Subrecipients.
III. Administration. The Chief Executive Officer of GenTegra or Board of Directors shall designate an employee of GenTegra who is not an Investigator to administer this Policy. Such employee shall be referred to in this Policy as the “Administrator” and shall fulfill all obligations that are assigned to the Institutional Official under the Regulations.
IV. Existence of Financial Conflict of Interest. A financial interest exists if the Investigator or his or her spouse or dependent children (1) receives from an entity remuneration greater than $5,000 in the aggregate in the 12 months preceding the disclosure of such interest, including without limitation salary, consulting fees, and honoraria, (2) holds equity with a value greater than $5,000 in a publicly traded company, including without limitation stock, options, and other forms of ownership, (3) holds any equity interest (e.g., stock, stock option, or other ownership interest) in a private company, (4) receives income related to intellectual property rights and interests (e.g., patents, copyrights), or (5) receives travel that is sponsored or reimbursed by an entity other than GenTegra or the government or academic entity or affiliate; BUT EXCLUDING (i) salary, royalties, or other remuneration paid by GenTegra; (ii) any ownership interest in GenTegra; (iii) income from investment vehicles, such as mutual funds and retirement accounts, as long as the Investigator does not directly control the investment decisions made in these vehicles; and (iv) income from government or academic sources for seminars, lectures, teaching, and service on review panels or advisory committees. A financial interest becomes a “Significant Financial Interest” if the financial interest reasonably appears to be related to the responsibilities of the Investigator to GenTegra. A Financial Conflict of Interest (“FCOI”) is a Significant Financial Interest that the Administrator reasonably determines (i) is related to the Covered Research,
i.e., could be affected by the Covered Research or is in an entity whose financial interest could be affected by the Covered Research and (ii) could directly and significantly affect the design, conduct, or reporting of Covered Research.
V. Reports. All Investigators must submit to the Administrator a report that discloses all Significant Financial Interests in Covered Research: (1) when planning to participate in the Covered Research, not later than the submission of the application for the Covered Research, (2) annually if participating in Covered Research, on or about June 30, and (3) as soon as possible, but not later than 30 days, after discovering or acquiring (e.g., through purchase, marriage, or inheritance) a new Significant Financial Interest. The Administrator shall review each report promptly after submission by the Investigator and shall inform the Investigator if a FCOI exists. If the Investigator eliminates the FCOI (which is not always possible or desirable) and revises and resubmits the report to the Administrator, then no further action is needed. However, if the FCOI continues, then the Administrator shall take the actions described below in this Policy.
VI. Conflict Management and Disclosure. If a FCOI exists, then the Administrator shall take the following actions prior to any expenditure of funds under the Covered Research to which the FCOI relates or, if the Covered Research is in progress and the FCOI is newly disclosed, then not later than 60 days after the FCOI is disclosed:
- Develop, implement, and administer a management plan that specifies the actions that have been taken, and shall be taken, to manage the FCOI during the period of the Covered Research. The Regulations provide the following non-limiting examples of conditions or restrictions that might be imposed by the Administrator to manage a FCOI (i) public disclosure of the FCOI (e.g., when presenting or publishing the research); (ii) for research projects involving human subjects research, disclosure of the FCOI directly to participants; (iii) appointment of an independent monitor capable of taking measures to protect the design, conduct, and reporting of the research against bias resulting from the FCOI; (iv) modification of the research plan; or (v) change of personnel or personnel responsibilities, or disqualification of personnel from participation in all or a portion of the research.
- Disclose on the GenTegra website the following information: the Investigator’s name; the Investigator’s title and role with respect to the research project; the name of the entity in which the significant financial interest is held; the nature of the significant financial interest; and the approximate dollar value of the significant financial interest (dollar ranges are permissible: $0–$4,999; $5,000–$9,999; $10,000–$19,999; amounts between $20,000–$100,000 by increments of $20,000; amounts above $100,000 by increments of $50,000), or a statement that the interest is one whose value cannot be readily determined through reference to public prices or other reasonable measures of fair market value. This information shall be updated annually and within 60 days after a new FCOI is disclosed to the Administrator. The website shall note that the information provided is current as of the date listed and is subject to updates, on at least an annual basis and within 60 days after GenTegra identifies a new FCOI. The information posted on the website will remain for at least 3 years after the initial post.
- Provide to the appropriate PHS agency a report regarding the FCOI. The report shall include sufficient information to enable the PHS agency to understand the nature and extent of the financial conflict, and to assess the appropriateness of the management plan. Elements of the FCOI report shall include, but are not necessarily limited to the following: (i) project number; (ii) PD/PI or Contact PD/PI if a multiple PD/PI model is used; (iii) name of the Investigator with the FCOI; (iv) name of the entity with which the Investigator has a FCOI; (v) nature of the financial interest (e.g., equity, consulting fee, travel reimbursement, honorarium); (vi) value of the financial interest (dollar ranges are permissible: $0–$4,999; $5,000–$9,999; $10,000–$19,999; amounts between $20,000–$100,000 by increments of $20,000; amounts above $100,000 by increments of $50,000), or a statement that the interest is one whose value cannot be readily determined through reference to to public prices or other reasonable measures of fair market; (vii) a description of how the financial interest relates to the Covered Research and the basis for GenTegra’s determination that the financial interest conflicts with such research; and (viii) a description of the key elements of GenTegra’s management plan, including: (A) role and principal duties of the conflicted Investigator in the Covered Research; (B) conditions of the management plan; (C) how the management plan is designed to safeguard objectivity in the Covered Research; (D) confirmation of the Investigator’s agreement to the management plan; (E) how the management plan will be monitored to ensure Investigator compliance; and (F) other information as needed.
- In addition, for any FCOI previously reported by GenTegra with regard to ongoing Covered Research, GenTegra shall provide to the appropriate PHS agency an annual FCOI report that addresses the status of the FCOI and any changes to the management plan for the duration of the Covered Research. The annual FCOI report shall specify whether the FCOI is still being managed or explain why the FCOI no longer exists. GenTegra shall provide annual FCOI reports to the appropriate PHS agency for the duration of the Covered Research (including extensions with or without funds) in the time and manner specified by the PHS agency.
VII. Training Requirement. GenTegra shall inform each Investigator of this Policy, the Investigator’s responsibilities regarding disclosure of Significant Financial Interests, and of the Regulations, and shall require each Investigator to complete the most recent NIH training module, which at present is available on line https://grants.nih.gov/grants/policy/coi/tutorial2018/story_html5.html, to learn relevant policies prior to engaging in Covered Research and thereafter at least every four years, and immediately when any of the following circumstances apply: (1) GenTegra revises this Policy or any procedures in a manner that affects the requirements of Investigators; (2) an Investigator is new to GenTegra; or (3) GenTegra finds that an Investigator is not in compliance with this Policy or a management plan instituted by the Administrator.
VIII. Procedures for Subrecipients. If GenTegra conducts Covered Research through a subrecipient (e.g., subcontractors), GenTegra must take reasonable steps to ensure that any subrecipient Investigator complies with this Policy and the Regulations by incorporating as part of a written agreement with the subrecipient terms that establish (1) that this Policy will apply to Investigators of the subrecipient, (2) time periods for the subrecipient to submit disclosures of Significant Financial Interests, which time periods shall allow sufficient time for GenTegra to comply with its requirements under this Policy, (3) that the subrecipient will accept any determination by the Administrator that a FCOI exists and shall enforce on its Investigators any management plan established by the Administrator. Alternatively, at the discretion of the Administrator, GenTegra may accept the FCOI policy of a subrecipient, provided that such policy complies with the Regulations, and that GenTegra and the subrecipient enter into a written agreement in which the subrecipient provides written certification that the policy complies with the Regulations, the subrecipient agrees to the other requirements set forth above, and the subrecipient agrees to any other terms and conditions required by the Administrator to ensure that GenTegra complies with the Regulations.
IX. Noncompliance. If GenTegra discovers that an Investigator has failed to disclose a Significant Conflict of Interest within the timelines set forth in this Policy, or if an Investigator fails to comply with a management plan established under this Policy, then GenTegra shall remedy such noncompliance and conduct a retrospective review as required under the Regulations. In such event, the Administrator shall refer to the Regulations for all necessary details and procedures.
X. Enforcement. Any violation of this Policy by an Investigator may result in disciplinary action by GenTegra, up to and including termination of employment.
XI. Public Disclosure and Records. GenTegra shall publicly disclose this Policy on its website, as required by the Regulations. All reports and other records relating to this Policy shall be retained for a period of at least 3 years from the date that the last payment is received for the applicable Covered Research. Such records shall be available for audit by the PHS as set forth in the Regulations.
