Bst DNA Polymerase (regular)

Contact us

Description:
rBst DNA Polymerase is the product of the DNA poll gene of the thermophilic bacterium Bacillus stearothermophilus (Bst). As an enzyme, it contains the 5´ -> 3´ polymerase activity, but lacks the 5´ -> 3´ exonuclease domain. It also has optimal activity at 65°C and can be used to synthesize DNA in regions that containing template secondary structure or high GCs where other non-thermostable DNA polymerases may fail in sequencing. Therefore, rBst DNA Polymerase is useful in replicating difficult templates in various applications.

Application:
- Isothermal DNA amplification by the method of:
· loop-mediated isothermal amplification (LAMP)
· whole genome amplification (WGA)
· ramification amplification (RAM)
- Random-primed DNA labeling
- Labeling by fill-in 5'-overhangs of dsDNA
