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
