Detailní popis

Thermo ScientificBsm DNA Polymerase, Large Fragment, is a portion of DNA polymerase of Bacillus smithii, which catalyzes 5'=>3' synthesis of DNA and lacks 5'→3' and 3'→5' exonuclease activities. Bsm DNA Polymerase, Large Fragment, has a strong strand displacement activity and is active in a wide range of temperatures from 30°C to 63°C, with an optimum of activity at 60°It is an enzyme with high functional similarity to Bst DNA Polymerase, Large Fragment, and can replace it in most applications.

Not suitable for use in PCR.


  • Thermophilic DNA polymerase with strong strand displacement activity


  • Isothermal DNA amplification by the method of:
    • Loop-mediated isothermal amplification (LAMP) (see Reference1, 2)
    • Whole genome amplification (WGA) (see​ Reference3)
    • Ramification amplification (RAM) (see​ Reference4)
  • Random-primed DNA labeling
  • Labeling by fill-in 5'-overhangs of dsDNA


Use of this enzyme in certain applications may be covered by patents and may require a license.
