Bst DNA Polymerase exo- is a recombinant DNA polymerase from Bacillus stearothermophilus. Bst DNA Polymerase is purified from an E.coli strain carrying a plasmid with the cloned gene encoding large fragment of DNA polymerase. It contains the 5´-> 3´ polymerase activity, but lacks 5´-> 3´ exonuclease activity. For this reason, Bst DNA Polymerase can be effectively used in chain displacement reaction at high temperature, 65°C.
Applications- Isothermal amplification (LAMP)- Applications requiring strand-displacement DNA synthesis- DNA sequencing through high GC regions- Rapid sequencing from nanogram amounts of DNA template 120 unit/㎕ in 10 mM Tris-HCl, pH8.0, 50 mM KCl, 0.1 mM EDTA, 1 mM DTT, 0.1% Triton X-100, and 50% Glycerol.
