Thermo Scientific Uracil-DNA Glycosylase (UDG, UNG) catalyzes the hydrolysis of the N-glycosylic bond between uracil and sugar, leaving an apyrimidinic site in uracil-containing single or double-stranded DNA (see Figure 1 in Supporting Data). The enzyme shows no activity on RNA.


Active in Thermo Scientific buffers for restriction enzymes and thermophilic polymerases


• Control of carry-over contamination in PCR
• Glycosylase mediated single nucleotide polymorphism detection (GMPD)
• Site-directed mutagenesis
• As a probe for protein-DNA interaction studies
• SNP genotyping
• Cloning of PCR products
• Generation of single strand overhangs of PCR products and cDNA


The abasic sites formed in DNA by Uracil-DNA Glycosylase may be subsequently cleaved by heat, alkali-treatment or endonucleases that cleave specifically at abasic sites. UDG (UNG) is active in the presence or absence of divalent cations.
