General description

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. Our 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 DNA Polymerase (formerly KOD HiFi DNA Polymerase) is a recombinant form of Thermococcus kodakaraensis KOD1 DNA polymerase. KOD is a high fidelity thermostable DNA polymerase that amplifies target DNA up to 6 kbp with superior accuracy and yield for PCR applications. The enzyme′s 3′→5′ exonuclease-dependent proofreading activity results in a lower PCR mutation frequency than any other commercially available DNA polymerase. The elongation rate and processivity are 5 times and 10 to 15 times higher, respectively, than for Pfu DNA polymerase, resulting in highly accurate and robust yield, in a short reaction time. The enzyme generates blunt-ended PCR products suitable for cloning with the Novagen Perfectly Blunt® and LIC Vector Kits.

Application

KOD DNA Polymerase has been used in high fidelity polymerase chain reaction (PCR) to amplify desired severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) N constructs.
