Incubation of 10 units of Klenow with supercoiled plasmid DNA produced no nicked molecules after 20 hours at 37 ☌ as determined by agarose gel electrophoresis analysis. Klenow retains the polymerization fidelity of the holoenzyme without degrading 5 termini. The enzyme lacks the 53 exonuclease activity of intact DNA polymerase I. The enzyme is greater than 98 % pure as indicated by SDS-polyacrylamide gel electrophoresis and contains no detected endonuclease activity. Klenow Fragment is the large fragment of DNA Polymerase I that retains its 53 polymerase, 35 exonuclease and strand displacement activities. Dissolve 0.1 - 4 μg of digested DNA in 1x Reaction Buffer supplemented with 40 μM each dNTPĥ00 mM Tris-HCl pH 7.6 at 25 ☌, 50 mM MgCl 2 and 10 mM DTT.Įxcessive amounts of enzyme or longer reaction times may result in recessed ends due to the 3'→5' exonuclease activity of the enzyme.Klenow retains the polymerization fidelity of the holoenzyme without degrading 5' termini. The enzyme lacks the 5'→3' exonuclease activity of intact DNA polymerase I. Klenow Fragment is the large fragment of DNA Polymerase I that retains its 5'→3' polymerase, 3'→5' exonuclease and strand displacement activities.
