Description
Quantity: 100 U
Unit Size: Each
Double and single-stranded dU-containing DNA are substrates for Uracil-DNA Glycosylase whereas RNA and normal dT-containing DNA are not.Uracil-DNA Glycosylase can also be used to increase the cloning efficiency of PCR products having dU-containing primers incorporated into them as well as increasing the efficiency of site-directed mutagenesis.The Uracil-DNA Glycosylase derived from Gadus morhua has all the attributes of the enzyme derived from E. coli with the added benefit of being heat-labile. It is completely and irreversibly inactivated after 10 minute incubation at 50°C.Purity:The enzyme is chromatographically purified and tested for contaminating endonucleases and exonucleases.Storage Buffer:20 mM Tris-HCl pH 7.5 (25°C), 50 mM NaCl, 0.4% non-ionic surfactant, 7 mM DTT, 0.1 mM EDTA, 50% Glycerol.Assay Conditions:The reaction mixture contains 70 mM Tris-HCl, pH 8.0, 10 mM NaCl, 1 mM EDTA, 100 μg/mL BSA, ^3H-dUTP labeled DNA, and Uracil-DNA Glycosylase. Incubation is at 37°C for 1 hour.Unit Definition:One unit is the amount of enzyme required to liberate 1 nmol uracil from dU-containing DNA in one hour at 37°C.Concentration:1 unit/μLApplications:
• Study of DNA repair and mutation detection.
• Increase cloning efficiency of PCR products.
• Increase the efficiency of site-directed mutagenesis.
• Study of protein-DNA interactions.Source:Recombinant from Gadus morhua (cod liver)
