Hi-throughput dUTP qPCR Mix, MDX031

Application: qPCR Specimen Type: PCR,qPCR,dU Containing Concentration: 2x High Concentration: No Wet: Yes
Glycerol-Free: NoNo Lyo-Ready: No Air-Dryable: No Dryable: No Sustainability:

qPCR mix containing Taq polymerase, reaction buffer, dNTP/dUTP mix and MgCl2, developed to remove background PCR product contamination.

Available in 5 mL (500 Rxns) or 100 mL (10,000 Rxns) aliquots


Hi-throughput dUTP qPCR Mix contains Taq DNA polymerase, reaction buffer, dNTP, MgCl2, stabilizers and PCR enhancers. However, some of the dTTPs in the dNTP mix has been substituted for dUTP, so that Uracil DNA Glycosylase (UDGase) (MDX054) can be added to carry-over qPCR contamination. This makes Hi-throughput dUTP qPCR ideal for multiplex assays on open, automated, high-throughput instruments.

FAQs: Hi-throughput dUTP qPCR Mix

As qPCR can amplify tiny amounts of DNA, preventing contamination is essential, as even small amounts of qPCR contamination can produce false positives. Cross-over qPCR contamination can include cross-contamination from other samples, contamination from elsewhere in the laboratory, and carryover qPCR contamination from amplification products and primers used in prior qPCR experiments. The latter causes most of the false positive results seen in qPCR. Preventing contamination can be difficult and so laboratory procedures must be in place to ensure DNA from one assay is not re-amplified in subsequent assay.

Uracil DNA Glycosylase can specifically degrade products that have already been through the qPCR process and have incorporated dUTP, leaving native nucleic acid templates intended for amplification intact. Uracil DNA Glycosylase activation occurs as the first step of qPCR at a 50°C incubation for 2 minutes and then the Uracil DNA Glycosylase is denatured when the temperature increases to 95°C during hot-start activation.

Uracil-DNA glycosylase (UDG or UDGase) is a family of enzymes comprising six sub-families. Family I UDGase enzymes are called UNG (uracil-N-glycosylase gene), so there is no difference, the terms UDG and UNG are commonly used interchangeably because they perform the same function in qPCR—namely to prevent carryover qPCR contamination.

Total elimination of contaminants is not always accomplished using this technique, particularly where PCR product length is short, which is a common situation in qPCR assays. In addition, there is the possibility, particularly when the initial sample contains only one or a few target molecules, that inclusion of UDG may reduce amplification efficiency and thereby delay detection and so reduce sensitivity.
