WebMar 5, 2007 · Q6: Can DNA Polymerase I, Large (Klenow) Fragment be heat inactivated? A6: Yes. Add 10 mM EDTA to chelate the Mg2+ cofactor, which protects the DNA ends as they "breathe" while the temperature is increased. Then heat at 75°C for 20 minutes. (Heat inactivation in the absence of EDTA accelerates the 3' > 5' exonuclease activity.) WebApr 10, 2024 · To hinder the switch between the two Klenow activities, the inactivation of the 3’-5’ exonuclease action by the introduction of two site-specific mutations (D355A, E357A) was previously reported . However, it should be noted that this inactivation does not necessarily abolish the binding of DNA by the proofreading domain of Klenow enzyme.
