Amplification of DNA fragments by DNA polymerase to produce millions of copies

PCR (polymerase chain reaction) utilizes the ability of naturally occurring DNA polymerases to extend short single-stranded primers that hybridize to the target template DNA. Despite its wide utility, most commercially available PCR reagents are remarkably similar, with any performance difference among them being attributed to differences in buffer formulation or enzyme concentration. These reagents contain wild-type enzymes, isolated from nature without modification. Roche offers the KAPA PCR reagents containing DNA polymerase and other enzymes selected through our Directed Evolution Technology to deliver high-quality results for specific PCR applications.

Roche offers the KAPA PCR reagents optimally suited for a variety of applications. KAPA HiFi PCR Kits , which use KAPA HiFi DNA Polymerase engineered for high fidelity and robustness, are used specifically for library amplification.

Overview

Quantitative real-time PCR (qPCR) enables the detection and quantification of PCR products in real time and is used widely in gene expression studies due to its high sensitivity, reproducibility and wide dynamic range. The technique uses double-stranded DNA (dsDNA)-binding dyes or target-specific fluorescently labeled primers and probes that hybridize with the target sequence to measure the relative amount of DNA. Most commercially available qPCR reagents contain wild-type, unmodified DNA polymerase, but these enzymes were never intended as tools for use in molecular biology.  The performance differences among commercial qPCR kits are the result of differences in factors like buffer formulation and/or enzyme concentration.

Roche offers KAPA qPCR reagents containing DNA polymerase and other novel enzymes specifically selected through our directed evolution technology for qPCR applications. These confer significant improvements to reaction efficiency, sensitivity, speed, and signal-to-noise ratio.
