Klenow Fragment (5 units/µl)
10x Reaction Buffer

Klenow Fragment is the large fragment of DNA Polymerase I that retains its 5'→3' polymerase, 3'→5' exonuclease and strand displacement activities. The enzyme lacks the 5'→3' exonuclease activity of intact DNA Polymerase I.

Klenow Fragment 3'→5' exo^- is a genetically engineered product of E. coli DNA polymerase I that catalyzes the 5'→3' synthesis of DNA but lacks its 3'→5' and 5'→3' exonuclease activities. The enzyme is recommended for second strand synthesis, particularly for incorporation of fluorescently labeled nucleotide analogs into DNA.
