Uracil DNA Glycosylase
Uracil DNA Glycosylase (uracil-N-glycosylase) removes uracil residues from the sugar moiety of single- and double-stranded DNA without destroying the phosphodiester backbone, preventing its use as a hybridization target or as a template for DNA polymerases. UDG will not remove uracil from RNA.
Applications: Helps to eliminate carryover contamination in PCR, resulting in fewer false positive results (1,2) for cloning PCR fragments (3).
Source: Purified from E. coli expressing the E. coli ung gene on a plasmid (4,5).
