Klentaq-S LA is a DNA polymerase mixture containing Klentaq-S, a mutant of Klentaq that has the feature of incorporating both dNTPs and ddNTPS.  It can be used in Pyrophosphorolysis-Activated Polymerization (PAP) for excellent specificity of primer binding.  The Long-Accurate feature allows for amplification of longer products with higher fidelity and accuracy.  LA enzymes are not recommended for use with dUTP.
