DAQ™ E.coli Uracil-DNA Glycosylase

Removing Uracil-containing DNA
Elimination of carry-over contamination
Applied to PCR based diagnostics for highly accurate result


DAQ™ Uracil-DNA Glycosylase excises Uracil from dU-containing DNA by cleaving the N-glycosidic bond between the uracil base and the sugar backbone. This cleavage generates alkali sensitive apyrimidinic sites that are blocked from replication by DNA polymerase or prevented from becoming a hybridization site. Double and single-stranded dU-containing DNA are substrates for Uracil-DNA Glycosylase whereas RNA and normal dT-containing DNA are not.
DAQ™ Uracil-DNA Glycosylase is useful to reduce the carry-over contamination in PCR based diagnostics.
