GenTegra-DNA is a water soluble chemical matrix that when added to purified DNA allows it to be air-dried to form a solid matrix which coats, preserves and protects DNA in the dry state at ambient temperatures. The protection is near perfect at the extremes of temperature (-80°C to +56°C) for many years. GenTegra-DNA is especially valuable and effective at protecting against the high temperatures likely to be encountered when shipping samples. Studies prove conclusively that GenTegra-DNA protects DNA better than storage at -20°C or -80°C and you save valuable freezer space. GenTegra-DNA has been protecting DNA samples since 2009 and is protected by an awarded US Patent. All GenTegra-DNA products have an expected shelf life of greater than 3-years at ambient temperatures. Accelerated temperature time studies show protection equivalent to >20 years. GenTegra-DNA has been protecting DNA since 2008 and is protected by an awarded US Patent. No need for a desiccant, ice or dry ice when shipping. And because of the stability at ambient temperatures it simply does not matter if the sample is delayed in shipment, it will still arrive perfectly intact and ready to use.
Once the purified DNA has been combined with the GenTegra-DNA matrix and dried it is stable and protected. And once dried it stays dry because it is not hydroscopic and will not take up water. Long term archiving of the DNA sample does not require either humidity control or desiccant to keep the DNA safe.
