Excellgen/Exonuclease Deficient T4 DNA Polymerase/EG-219/250 Units
来自 : 发布时间:2024-11-14
Description

T4 DNA Polymerase catalyzes the extension of a primed DNA template (in the presence of template and primer) in the 5′→ 3′ direction. This D219A mutant T4 DNA Polymerase does not possess either 3\'->5’ (proofreading) and 5′→ 3′ exonuclease activities.

Applications

Random mutagenesis

SourceA recombinant E. coli strain carrying a cloned gene 43 (D219A mutant) of bacteriophage T4.
Unit DefinitionOne unit is defined as the amount of enzyme that will incorporate 10 nmol of dNTP into acid-precipitable material in 30 minutes at 37°C.
Components
  • Exonuclease Deficient T4 DNA Polymerase: 3,000 U/ml in 100 mM KPO4, 1.0 mM DTT, 0.1 mM EDTA, 50% glycerol, pH 6.5 @ 25°C
  • 10X Reaction Buffer: 500 mM NaCl, 100 mM Tris-HCl, 100 mM MgCl2, 10 mM DTT, pH 7.9 @ 25°C
Quality ControlThe absence of endodeoxyribonucleases confirmed by appropriate quality tests.
Storage Condition

-20 °C
