E. coli Uracil-N-glycosylase (UNG) hydrolyses the release of free uracil from uracil-containing DNA. UNG efficiently hydrolyses single or double-stranded DNA, but not from oligomers (6 or less bases).
Source: Recombinant E. coli UNG purified from an E. coli expressing clone.
Storage: For long term storage UNG/dUTP blend should be stored at -20°C in a constant temperature freezer. When stored under these conditions, the reagent is stable for 2 years. Avoid repetitive freeze-thaw cycles.
