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.) WebT4 DNA Polymerase ( NEB #M0203 ) or Klenow ( NEB #M0210) will fill in a 5´ overhang and chew back a 3´ overhang. The Quick Blunting Kit ( NEB #E1201) is optimized to blunt and phosphorylate DNA ends for cloning in less than 30 minutes.
