Product picture of PCRBIO's endpoint range

PCR

The process of DNA manipulation has been in use for over half a century since the advent of restriction enzymes. However it was not until Kary Mullis demonstrated the process of the Polymerase Chain Reaction (PCR) in 1983 that the manipulation of DNA was sufficiently functional for it to change the landscape of biological research.

PCR continues to be the gold standard for DNA manipulation and is still present in the majority of biological research laboratories. Although PCR is principally unchanged, the technique has developed over time so that many different polymerases are available for use depending on the application. The functionality for these applications also continues to improve as development scientists find ways to improve the reliability, yield, specificity, speed and sensitivity of DNA Polymerases.

PCR Biosystems offer a range of polymerases to suit your needs and application. These enzymes are developed using the latest advances in polymerase and buffer technology to provide high-performance kits and reagents that scientists can rely on.

Colony PCR

Molecular cloning techniques require some method of screening colonies for the presence or absence of the DNA  insert. Traditionally this has been carried out with restriction enzyme digest, however colony PCR…

Cloning

Molecular cloning is a collection of experimental methods used in molecular biology to assemble recombinant DNA molecules and to direct their replication within host organisms. A molecular cloning reaction is typically comprised of two components which…

Long Range PCR

Long range PCR refers to the amplification of DNA targets over 5kb in length which typically cannot be amplified using routine PCR methods or reagents. Traditionally, long range PCR has…

GC-Rich PCR

DNA templates with high GC content (>65%) can affect the efficiency of PCR due to the tendency of these templates to fold into complex secondary structures. This is due to…
