| http://www.w3.org/ns/prov#value | - DNA is a very stable molecule and it can be stored for prolonged times provided there are no nuclease contamination. nuclease contamination comes due to microbial contamination so storage under sterile conditions is a necessity. can store at -20/ -80 C for months. however repeated freeze thawing might affect its stability. aliquoting can overcome this problem. rough handling may shear the DNA. -SH
