Uracil-DNA Glycosylase from Psychrophilic marine bacterium, Recombinant
Cat No.
COV-001
Description
UDG (Uracil-DNA Glycosylase) catalyses and hydrolyses uracil base and N- glycosidic bond of the sugar phosphate skeleton which belong to single or double-stranded DNA containing dU. Thus, free uracils are released and the base-free sites are dissociated easily by hydrolysis. Heat-labile UDG steming from psychrophilic marine bacterium, is sensitive to high temperature and therefore inactivates enzymes irreversibly when temperature over 50°C, which is suitable for PCR/QPCR, RT- PCR /RT-QPCR system.
