It is said that, unless specified, restriction enzymes should be stored in -20 and storing in -80 will spoil the enzymes. Why is that so?
Aren't restriction enzymes stored in glycerol to protect it from freezing in -20?
Propably this is the reason why they will spoil when frozen in -80. I think so.
I hope I helped.
-20 degrees with glycerol to avoid freeze-thaw cycles. Keep to the manufacturer's recommendations.
I need to do epistasis analysis between two sets of SNPs (each contains ~1000 SNPs). I am interested in pairwise interactions between the SNPs on different sets and not between SNPs on same set. I...
