ThermoStartTM Bst DNA Polymerase

Description

ThermoStartTM Bst DNA polymerase source from Bacillus stearothermophilus DNA polymerase I. it has no 5'-3' exonuclease activity, but enhanced its 5'-3' DNA polymerase activity and strand replacement activity. After genetic engineering, the enzyme has increased the hot start function, which has no activity below 60 degrees. Compared with wild-type Bst DNA polymerase, the enzyme has greatly improved in amplification speed, yield, salt tolerance and thermal stability, and increased dUTP tolerance. It is very suitable for pollution-proof isothermal amplification reactions, such as lamp.
