Bst DNA Polymerase (large fragment)

Description:
A recombinant E. coli strain carrying the BST DNA Polymerase gene (large fragment).
 

Figure: MCLAB Bst DNA Polymerase (large fragment) shows Higher strand -displacing polymerase activity than other two vendors' products.

Application:
- Sequencing through problematic secondary structures

Source:
Bst DNA Polymerase (large fragment) is the portion of the Bacillus stearothermophilus DNA Polymerase protein that contains the 5´-> 3´ polymerase activity, but lacks the 5'->3' exonuclease domain.
