DNA Polymerase I Large (Klenow) Fragment

Details for Product No. ABIN3188231,
DNA Amplification (DNA Amp)
Characteristics DNA Polymerase I Large (Klenow) Fragment is the large fragment of E. coliDNA Polymerase I (abm Cat. No. G469). The Klenow Fragment retains the DNA-dependent DNA polymerase activity of the E. coli DNA Polymerase I but lacks the 5'→3' exonuclease activity. With its inherent 3'→5' exonuclease activity, Klenow possesses the polymerization fidelity of the holoenzyme without degrading 5'-termini.
Components Enzyme supplied with 10X Reaction Buffer
Unit Definition One unit is defined as the amount of DNA Polymerase I Large (Klenow) Fragment that catalyzes the incorporation of 10 nmol of dNTP into acid insoluble material in 30 minutes at 37°C using poly(dA-dT):poly(dA-dT) as a template:primer.
