Overview

Description

Salini UNG® Uracil-N-Glycosylase is a unique heat-labile enzyme. The protein sequence originates from the bacteria genus Salinivibrio which is frequently found in hypersaline environments. Uracil-N-Glycosylase (UNG) efficiently eliminates uracil from single- or doublestranded DNA by catalyzing the hydrolysis of the N-glycosylic bond and leaving an abasic site. This property is widely used as a part of PCR carryover contamination prevention strategy. Salini UNG® is a genetically modified enzyme including a Stability TAG - Solis BioDyne’s proprietary and patented polypeptide stabilization technology that makes all our proteins extremely stable at room temperature [1].

Applications

  • Widely used to eliminate carryover contamination in PCR and LAMP
  • Enhancer of cloning efficiency of PCR products
  • Site-directed mutagenesis
  • Protein-DNA interaction studies
  • Glycosylase-mediated single nucleotide polymorphism detection (GMPD)
  • Study of DNA repair and mutation detection
  • SNP genotyping

Properties

Concentration: 1 U/µl

Source: Purified from an E.coli strain that carries an overproducing plasmid containing a Salini UNG® Uracil-N-Glycosylase gene.

Storage and dilution buffer: 50% glycerol (v/v), 25 mM Tris-HCl pH 7.5, 100 mM KCl, 0.1 mM EDTA, 1 mM DTT and stabilizers.

Recommendations for use

Working concentration: For qPCR application we recommend to use Salini UNG® Uracil-N-Glycosylase at a final concentration of 0.025-0.04 U/μl, for endpoint PCR application at a final concentration of 0.005-0.01 U/μl.

Reaction temperature: If you setup reaction at room temperature, no additional treatment step is required. If you setup reaction on ice add UNG treatment step prior amplification: 30 seconds at 25 °C. Working temperature 25-40 °C.

Inactivation: 5 min at 70 °C.
