Hi I just stumbled here from Boing Boing and have no experience with your DNA gel. So I don't know what would happen to the quality of your gel sample if it were to be frozen. However, if freezing the sample without damaging it is possible, you might try this for extracting the cores:
First, freeze the gel-straw. Then, hold it gently in your hand so that your body heat slightly warms the plastic straw, but leaves the gel inside still frozen. This should create a slippery film between the wall of the straw and the gel. Finally, using a sterile plunger (pipette?) of the appropriate size, push the gel out of the straw and into your chosen container. I hope this helps you guys, Brian
