KlenTaq

KlenTaq is a truncated version of Taq DNA Polymerase, lacking its first 280 amino acids. The enzyme catalyzes the polymerization of nucleotides into duplex DNA in 5'→3' direction in the presence of magnesium but lacks the 5'→3' exonuclease activity of Taq polymerase. The enzyme is purified by an additional separation process to reduce contaminating bacterial DNA sequences. In addition to routine PCR, KlenTaq is recommended for genotyping and primer extension. Compared to Taq the enzyme shows an improved fidelity and thermostability.
