설명
Bst DNA Polymerase is derived from Bacillus stearothermophilus DNA Polymerase I. It possesses 5'→3' DNA polymerase activity and strong strand displacement activity but lacks 5'→3' exonuclease activity. It is suitable for DNA strand displacement reactions, isothermal amplification techniques such as LAMP (Loop-mediated Isothermal Amplification), and rapid sequencing.
WS Bst DNA Polymerase is a hot-start version of Bst DNA Polymerase developed using reversible modification technology. It effectively inhibits DNA polymerase activity at room temperature, allowing for reaction setup and operation at ambient conditions without non-specific amplification, thereby improving reaction efficiency. Furthermore, the enzyme releases its activity at elevated temperatures, eliminating the need for a separate activation step.
