Uracil-DNA Glycosylase, also known as UDG or UNG, removes free uracil residues from uracil-containing DNA (single- and double-stranded) without destroying the sugar-phosphodiester backbone.UDG effectively prevents the subsequent use of UDG-treated DNA as a hybridization target or as a template for DNA polymerases.

Treatment of 0.1 ㎍ of uracil-containing DNA with 1 unit UDG for 10 min at 37°C can not be used as a template for next round of PCR. UDG is active over a broad range of pH and heat inactivated > 95% by incubation at 95°C for 10 min.

Uracil-DNA Glycosylase gene is obtained from E.coli strain and recombinant enzyme is purified.
