Abstract: A modified thermostable Pol B DNA polymerase, produced by a reaction, under essentially aqueous conditions, of a thermostable Pol B DNA polymerase and a modifier reagent of Formula I wherein the reaction results in a thermally reversible inactivation of the thermostable Pol B DNA polymerase activity and the 3′-5′ exonuclease activity, which polymerase is suitable for hot-start PCR. Also disclosed are the method for the modification, a polynucleic acid amplification method and PCR reaction mixture and kit comprising the modified thermostable Pol B DNA polymerase.
