Dutp/ung carryover prevention system
WebDec 1, 1996 · However, when using the dUTP/UNG carryover prevention system, the Tann must be maintained above 50°C, since high temperature denaturations are not utilized and UNG is active at or below temperatures of 50°C and will degrade DNA containing dUMP. The use of mixtures of dITP and dGTP allows for modulation of the Tann. WebIncorporate this glycosylase in your PCR containing dUTPs to minimize contamination from carryover products.

Dutp/ung carryover prevention system
Did you know?
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]. WebApr 20, 2024 · The efficiency of elimination of the carryover contamination of Cod-UNG-rRT-LAMP depends on (1) the incorporation of dUTP in the LAMP product that was responsible by Bst 2.0 Warmstart ® DNA polymerase and (2) the hydrolysis of uracils incorporated in the contaminants that was responsible by Cod-UNG. Therefore, we believe that different …
WebMay 30, 2024 · A current procedure makes use of dUTP incorporation instead of dTTP during amplification, which is preceded by treatment with a heat-labile uracil-N … WebThe assay also uses a dUTP/UNG carryover prevention system to avoid contamination of PCR products and subsequent false positive results.
