WebThe term UDG refers to a superfamily of enzymes comprising six sub-families. Family I UDG enzymes are called UNG, after the uracil-N-glycosylase gene [6]. The terms UDG and UNG are commonly used interchangeably because they perform the same function in qPCR—namely to prevent carryover contamination. The biological function is to remove uracil ... WebUNG is active on single- and double-stranded dU-containing DNA, but dUTP is not a substrate for UNG. Taq polymerase and other components of the PCR mixture are not affected by UNG treatment. Only carryover product will be removed with UNG treatment [8].
