M0210S, DNA Polymerase Large Fragment (Klenow) - 200 units

DNA Polymerase I, Large (Klenow) Fragment is a proteolytic product of E. coli DNA Polymerase I which retains polymerization and 3'→ 5' exonuclease activity, but has lost 5'→ 3' exonuclease activity. Klenow retains the polymerization fidelity of the holoenzyme without degrading 5' termini.
