Bsu DNA Polymerase Large Fragment

Product 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.


  • Strand displacement DNA synthesis
  • Random primer labeling
  • Second strand cDNA synthesis
  • dA-tailing
