Description

Thermolabile Uracil-DNA Glycosylase (tUDG) is a 25.5 KDa protein isolated from a recombinant E. coli strain bearing cloned UNDG gene from a psychrophilic marine bacterium. It hydrolyzes uracil-glycosidic bonds in single- or double-stranded DNA, creating alkali-sensitive abasic sites. These abasic sites can be hydrolyzed by endonuclease, heat, or alkali treatment. The enzyme is used in the preparation of PCR, RT-PCR and LAMP mixtures to prevent carryover contamination.
The enzyme is highly purified by affinity and anion-exchange chromatography. The enzyme is inactivated completely during 5 minutes at 55°С and does not interfere with the current reaction amplification products.

Benefits:

  • Prevents carryover contamination
  • Inactivated at 55°С

Area of applications:

  • Routine PCR
  • Routine RT-PCR
  • LAMP

Concentration:

  • 5 units/μl (500 units/μl for glycerol-free enzyme)

Storage and dilution buffer:

  • 20 mM Tris-HCl (pH 7.0), 0.5 mM EDTA, 100 mM KCl, 50% glycerol, 0.1 mg/ml BSA

Storage and transportation conditions:

  • From -24°С to -16°С – 1 year
