Bst II DNA Polymerase (Large Fragment, Glycerol Free) is a modified version of Bacillus stearothermophilus DNA polymerase. It has been engineered and expressed in Escherichia coli. This product exhibits strong 5'→3' DNA polymerase activity and strand displacement activity but lacks 5'→3' exonuclease activity，and the optimal reaction temperature is 65℃. lt is suitable for various isothermal amplification reactions, such as Loop-Mediated lsothermal Amplification (LAMP), Rolling Circle Amplification (RCA), Helicase-Dependent Amplification (HDA), etc. Compared to the wild-type enzyme, Bst II DNAPolymerase (Large Fragment, Glycerol Free) has a faster amplification rate, stronger dUTP tolerance, salt tolerance, and improved stability. 
       This product is glycerol-free and can be used for the preparation of various lyophilized reagents. Avoid repeated freeze-thaw.
