Heat-labile Uracil-DNA Glycosylase (Glycerol-Free)

Uracil-DNA Glycosylase, also known as UNG or UDG, is an enzyme that hydrolyses the N-glycosylic bond between the deoxyribose sugar and the base in uracil-containing DNA leaving an apyrimidinic site in DNA. Double and single-stranded dU-containing DNA are substrates for Uracil-DNA Glycosylase whereas RNA and normal dT-containing DNA are not. Contamination of PCR samples with amplicon DNA generated by previous reactions, “carry-over contamination”, is one of the major sources of false positive results. Heat-labile Uracil-DNA Glycosylase prevents carry-over contamination in PCR, qPCR, RT-qPCR, and RT-LAMP assays. Heat-labile UDG was derived from psychrophilic marine bacteria and is produced by recombinant expression in E. coil. Heat-labile Uracil-DNA Glycosylase (Glycerol-Free) is a glycerol free formulation of our regular Heat-labile UDG and is well suited for automated high throughput testing, lyophilization or where accurate pipetting of small volumes are crucial. Heat-labile Uracil-DNA Glycosylase (Glycerol-Free) is available in different sizes and concentrations.
