One of the challenges is to store DNA samples in such a way that the DNA is not degraded. Today, in many cases the samples are transported and/or stored in dark and cold areas with the addition of silica gel as an absorbent. Dr. Allen Van Deynze, a researcher at the University of California, Davis, was one of the first people who tested the possibility of using Drying Beads for transport and storage of DNA samples. The results were very positive and today many different trials with DNA samples are ongoing. Some first findings are showing us that leaf materials are dried perfectly, so that the degradation is quickly paused. Another advantage we found is that the leaves are very easily crushed, and no liquid nitrogen is needed during the DNA extraction.
