WebbA restriction enzyme may lose activity due to improper storage or handling. Here are solutions to help you prevent and address this issue. Confirm the expiration date, verify that the restriction enzyme has been stored at -20°C, and check the temperature of your freezer (do not allow temperatures to exceed -20°C, as multiple freeze-thaw cycles … WebbSticky ends are fragments of DNA where one strand, after being cleaved by restriction enzymes, is left over hanging another strand. It is cleaved assymetrically and can leave a 5′ or a 3′ overhang. These overhangs are termed ‘sticky’ because they can easily bind to free nucleotides.
