Description

Description

Bsu DNA Polymerase I, Large Fragment is a product of the Bacillus subtilis DNA polymerase I which lacks the N-terminal exonuclease domain (1-296 amino acids). It retains the 5´→ 3´ polymerase activity of DNA polymerase I but lacks the 5´→ 3´ exonuclease activity. This large fragment also lacks 3´→ 5´ exonuclease activity (1)

Applications
• Strand displacement DNA synthesis (2)
• Random primer labeling
• Second strand cDNA synthesis
• dA-tailing

Protein Purity
The physical purity of Bsu DNA Polymerase I, Large Fragment is ≥99% as assessed by SDS-PAGE with Coomassie® blue staining.

Product Source
E. coli strain expressing Bsu DNA Polymerase I gene lacking the N-terminal exonuclease domain.
