Omni Klentaq LA is a triple mutant of Klentaq polymerase that makes the enzyme resistant to the inhibitory effects of blood, soil, inhibitory foods, and fluorescent dyes. It remains functional in up to 20 - 25% whole blood, especially in the presence of one of our PCR Enhancer Cocktails. It can also tolerate some concentrations of crude soil extract where other enzymes fail. The Long-Accurate feature allows for amplification of longer products with higher fidelity and accuracy. LA enzymes are not recommended for use with dUTP.
