PCR involves replication of a DNA template by a thermostable DNA polymerase. The processivity, specificity, and fidelity of the polymerase enzyme used can influence the efficiency, reproducibility, and yield of the PCR reaction. High-fidelity PCR, utilizes a DNA polymerase with a low error rate and results in a high degree of accuracy in the replication of the DNA of interest. Fidelity is critical when accurate sequence amplification of the gene target is needed, for example, when direct sequencing or cloning for downstream protein expression. Unwarranted mutation could severely impact your studies. Our analysis has shown that KOD enzymes are an easy choice for fast, accurate and high-yielding PCR. EMD Millipore's molecular biologists work to develop and formulate polymerases offering the highest specificity, fidelity and yield during PCR amplification. In addition, optimized buffer compositions, convenient master mixes and cycling parameters provide additional ease of use and data reproducibility. KOD XL DNA Polymerase* is an optimized blend of KOD DNA Polymerase and a mutant form of KOD that is deficient in 3′→5′ exonuclease activity (Nishioka 2002). This enzyme mixture is designed for reliable amplification of long, complex targets with robust yield and high accuracy. It can also be used for incorporation of derivatized dNTPs in PCR amplicons (Sawai 2002, Sawai 2001). KOD XL DNA Polymerase generates a mixture of PCR products with blunt and 3′-dA overhangs, suitable for cloning with Novagen Perfectly Blunt®, AccepTor™, and LIC Vector Kits.
