Dutp/ung carryover prevention system
WebCarryover Prevention with dUTP not Recommended Deoxyuracil triphosphate (dUTP) is a poor substrate for the GeneAmp High Fidelity enzyme mix. Therefore, we do not recommend the UNG carryover prevention method with this system. HighFidelity_text.book Page 7 Wednesday, July 18, 2001 11:14 AM 8 Protocol for Amplification of Samples WebThe enzyme uracil-N-glycosylase (UNG, also referred to as UDG) can be added to a PCR premix to excise uracil from any contaminating PCR product, thereby preventing false positives. Each lot of dUTP is tested to ensure specific DNA amplification and the absence of nuclease activity. Longo, M.C. et al. (1990) Gene 93, 125–8.

This method modifies PCR products such that in a new reaction, any …
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].
WebA major source of PCR cross-contamination is carryover of PCR products in subsequent amplification reactions. One way to minimize such contamination is to include dUTP and uracil-DNA N-glycosylase in PCR. Here, we demonstrate this method with GoTaq® DNA Polymerase and suggest a protocol for routine laboratory use.
