尿嘧啶DNA糖基化酶(UDG)

¥0.00¥4,782.00

Uracil-DNA Glycosylase catalyzes the hydrolysis of the N-glycosylic bond between the uracil and sugar, leaving an abasic site in uracil-containing single or double-stranded DNA. The enzyme shows no measurable activity on short oligonucleotides (<6 bases), or RNA substrates.

Description

Description:
Uracil-DNA Glycosylase catalyzes the hydrolysis of the N-glycosylic bond between the uracil and sugar, leaving an abasic site in uracil-containing single or double-stranded DNA. The enzyme shows no measurable activity on short oligonucleotides (<6 bases), or RNA substrates.

Applications:

  • Control of carry-over contamination in PCR (1)
  • Glycosylase mediated single nucleotide polymorphism detection (GMPD) (2)
  • Site-directed mutagenesis (3)
  • As a probe for protein-DNA interaction studies (4)
  • SNP genotyping
  • Cloning of PCR products (5)
  • Generation of single strand overhangs of PCR products and cDNA
