BIOER BioReady Heat-labile UDG — Estimated US$66 / 500 U reference quantity (assumed; confirm pack)

BioReady Thermosensitive Uracil-DNA Glycosylase (UDG) is derived from recombinant cloning and expression in Escherichia coli. It effectively hydrolyzes uracil (U) in single-stranded or double-stranded DNA longer than 6 base pairs, with no activity on RNA. Its primary application is to prevent contamination of PCR amplification products. It works by replacing dTTP with dUTP in the PCR reaction, creating PCR amplification products containing dU bases. UDG then cleaves the dU bases in these amplification products, creating abasic sites, preventing the DNA strand from serving as a template for subsequent PCR, thus achieving the goal of preventing PCR product contamination. Additionally, this thermosensitive UDG becomes inactive in the subsequent 50°C reverse transcription or 95°C pre-denaturation steps without affecting the amplification of the template.

Product details

BioReady Heat-labile UDG（Uracil-DNA Glycosylase）catalyzes the release of free uracil from longer then 6bp dU-containing single-stranded or double-stranded DNA whereas RNA and normal dT-containing DNA. UDG excises uracil form dU-containing PCR product when Dttp replace with dUTP was incorporated into DNA. The resulting abasic sites are blocked from replication by PCR. It mainly used to prevent contamination of PCR amplification products. This enzyme is sensitive to heat. It can be completely and irreversibly inactivated after 10 min at temperatures above 50°C.
