| Description |
Gst DNA Polymerase is functionally equivalent to the large fragment of Bsm Polymerase I and Bst Polymerase I. Recombinant Gst DNA Polymerase (large fragment) has 5’-> 3’ polymerase activity, but lacks 5’->3’ exonuclease and 3'→5' exonuclease activities. Gst 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 such as rapid amplification of trace amounts of DNA templates for sequencing and LAMP.
