Find DNA polymerases and reagents for every PCR technique

What is PCR?

Polymerase Chain Reaction (PCR) is the method of choice for DNA amplification for nearly 40 years since Karry Mullis developed PCR in 1983. PCR is used to generate multiple copies of a DNA region. It is thus a crucial technique for all areas of molecular biology.

What are the different types of PCR?

Multiple types of PCR-based applications are used: to clone DNA, introduce specific mutations to DNA fragments by site-directed mutagenesis, modify DNA by introducing adaptors or specific sequences, to detect, identify, or quantify specific DNA targets, and even to quantify gene transcript (RNA) levels with adapted PCR techniques, such as reverse transcription-PCR (RT-PCR).

PCR continues to be the gold standard for DNA amplification and is still used in most biological research laboratories. Although PCR is principally unchanged, the technique has developed over time so that many different polymerases (e.g., Taq DNA polymerase, Pfu DNA polymerase, and derivatives) are available for use depending on the application and many of these polymerases are available as ready polymerase mixes, for reduced reagent handling during PCR-setup, or as hot-start DNA polymerases for increased amplification specificity. The functionality of these PCR applications also continues to improve as development scientists find ways to enhance the reliability, yield, specificity, sensitivity, and speed of DNA Polymerases.

At PCR Biosystems we continually develop our range of optimised DNA polymerases and high-performance kits and reagents to suit your needs and cover every PCR application.
