T4 DNA Polymerase
neb31 cloned at NEB recombinant 75 Heat

We are excited to announce that all reaction buffers are now BSA-free. NEB began switching our BSA-containing reaction buffers in April 2021 to buffers containing Recombinant Albumin (rAlbumin) for restriction enzymes and some DNA modifying enzymes. Find more details at www.neb.com/BSA-free.

T4 DNA Polymerase catalyzes the synthesis of DNA in the 5´→ 3´ direction and requires the presence of template and primer. 

  • Gap filling (no strand displacement activity)
  • Removal of 3’ overhangs or fill-in of 5’ overhangs to form blunt ends
  • Lacks 5’ —> 3’ exonuclease activity
  • Probe labeling using replacement synthesis
  • Singe-strand deletion subcloning
