Dutp/ung carryover prevention system
WebUracil-DNA Glycosylase (UNG) is suitable for preventing carryover contamination in PCR. This cross-contamination prevention technique involves incorporating deoxyuridine triphosphate into amplification products, permitting pretreatment of subsequent PCR mixtures with UNG. When a dUTP containing contaminant is present in later PCRs, 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 ...

Did you know?
WebUracil DNA Glycosylase (UNG or UDG) hydrolyzes N-glycosylic bonds between the deoxyribose sugars and uracil bases in uracil-containing DNA, leaving apyrimidinic sites in the DNA. UNG excises uracil from both single- and double-stranded dU-containing DNA but not from RNA. Incorporating UNG with dUTP in a PCR reaction can help minimize ... WebUse of modified nucleotides and uracil-DNA glycosylase (UNG) for the control of contamination in the PCR-based amplification of RNA. The inadvertent carryover of …

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 … WebNov 28, 2006 · The UNG technology is, to our knowledge, the only ‘closed vessel’ carry-over prevention method for PCR based diagnostic screening assays. In this paper we present, …
WebHowever carry-over contamination can be controlled by the following two steps: (i) incorporating dUTP in all PCR products (by substituting dUTP for dTTP, or by incorporating uracil during synthesis of primers; and (ii) …
WebThe 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—normally found in RNA—from DNA, creating free uracil and alkali-sensitive apyrimidic sites in DNA [2,6]. imdb tick tick tickWebThe ReadyMix has incorporated dUTP in place of TTP to facilitate carryover prevention.
