Field Sample Collection 2018-01-31T03:16:53+00:00

Field Sample collection without Cold Chain

Collecting samples in remote location can often be a challenge especially if the collection method requires the use of a cold chain to get the samples back to the laboratory. Paper collection cards offer a simple and convenient method of collecting sample and avoiding the hassles of a cold chain. GenTegra offers a card for every need whether you are collecting DNA, RNA or some other small molecule.

The Ahlstrom-Munksjö GenSaver™ card is the best choice when collecting DBS samples in the field. The GenSaver card provides superior protect for the DBS sample and protects the DNA from elevated temperatures and for oxidative damage while being stored. The GenSaver cards have the same Active Chemical Protection that is provided by GenTegra-DNA. The GenSaver card also support extraction yields that are 100% higher than the yields seen when using FTA cards for DBS collection. All the common card formats; 1-spot, 2-spot, 4-spot and others are available as well as custom cards when the existing formats do not meet you need. If you have a special format in mind contact GenTegra at info@gentegra.com

The Ahlstrom-Munksjö GenSaver™ card is the best choice when collecting DBS samples in the field. Because the GenSaver cards do not require cooling or freezing to protect the DNA they are especially convenient when sample collection is in areas where a cold chain is difficult to support. The blood sample is easily collected and simple air drying for a couple hours will normally prepare the DBS sample for shipment. To ensure the DBS is dry it is recommended that a silica gel desiccant packet be included with the sample cards. The desiccant packet will ensure the drying step is completed and keep the DBS dry during shipment. An air tight shipping package is the only other recommendation to assist in keeping moisture out of the package.

When collecting samples for small molecule identification or for short term transport of DNA we have the Ahlstrom-Munksjö GenCollect card. The GenCollect card is a plain paper collection card with no added chemistry. This card is useful for small molecule identification and has no chemistry added that might interfere with the MassSpec analysis.
We also offer a RNA collection card GenProtect RNA. If you have a need for collecting RNA is areas where a cold chain is not readily available we may be able to provide a card technology that will protect the RNA until the sample reaches the laboratory for analysis. Please contact us at info@gentegra.com if you are interested in a RNA collection card.
