Mechanism for M1282

  • Uracil DNA glycosylase
  • Monofunctional DNA glycosylase that catalyzes the hydrolysis of the N-glycosidic bond from deoxyuridine to release uracil
  • Active on ss and dsDNA
  • Heat inactivation not possible

    What are endonucleases and their applications?
E. coli Uracil-DNA Glycosylase (UDG) catalyses the release of free uracil from uracil-containing DNA. UDG efficiently hydrolyzes uracil from single-stranded or double-stranded DNA, but not from oligomers (6 or fewer bases).
Product Source
An E. coli strain that carries the UDG gene from E. coli.
Reagents Supplied

The following reagents are supplied with this product:

NEB # Component Name Component # Stored at (°C) Amount Concentration
  Uracil-DNA Glycosylase (UDG) M0280SVIAL -20 1 x 0.2 ml 5,000 units/ml
  UDG Reaction Buffer B0280SVIAL -20 1 x 1.5 ml 10 X
  Uracil-DNA Glycosylase (UDG) M0280LVIAL -20 1 x 1 ml 5,000 units/ml
  UDG Reaction Buffer B0280SVIAL -20 1 x 1.5 ml 10 X
Application Features
  • Treatment of 0.1 µg of uracil-containing DNA with 1 unit of UDG for 10 minutes at 37°C renders the DNA incapable of being copied by DNA polymerase. The enzyme can be 95% heat killed by incubation at 95°C for 10 minutes. Since UDG remains partially active following heat treatment at 95°C, it is recommended that uracil glycosylase inhibitor be added to prevent degradation of product DNA. Alternatively, reaction products can be immediately extracted with phenol/chloroform.
