The enzymes segment is divided into the ligases, phosphatases, polymerases
, proteases and proteinases, restriction endonucleases, reverse transcriptases, and other enzymes sub-segments.

sub-segments are high-fidelity DNA polymerase
, T4 DNA polymerase
, Taq DNA polymerase
, and other polymerases
Agilent's molecular biology solutions include PCR instrumentation, high fidelity polymerases
, and specialty enzymes, along with qPCR instrumentation and reagents, and market leading mutagenesis and cloning products.
Within the context of a living cell, DNA replication by polymerases
also initiates from primer sequences, but without either of these methods.
Several methods have been developed to measure the activity of DNA polymerases
, but complexity, time requirements, and specialized instrumentation have prevented their widespread use.
The sliding clamp then serves to anchor special enzymes called polymerases
to the DNA, ensuring efficient copying of the genetic material.
6) Automation of PCR along with the use of Taq polymerase
and other heat stable polymerases
, opened the door for various modifications of the technique including the development of real-time PCR assays, reverse transcription PCR (RT-PCR), multiplex PCR, and nested PCR all commonly used in clinical laboratories, forensic laboratories, and research facilities.
The invention also provides thermostable polymerases
and nucleic acids encoding thermostable polymerases
having altered fidelity, for example, high fidelity polymerases
and low fidelity polymerases
The genes in these blocks code for the 1918 flu's polymerases
, which are proteins crucial for a virus' replication in animal hosts.
Woodgate's laboratory recently discovered and purified polymerase
iota (pol [Iota], one of a superfamily of DNA polymerases
that synthesize short stretches of DNA and are relatively inaccurate--that is, they may allow the A, C, G, or T base moieties to be matched to an incorrect mate (for instance, matching G with T or A, rather than with its proper mate, C).
The DNA polymerases
contained in Kapa Biosystems' reagents have been engineered through a process of molecular evolution and possess unique amino acid modifications that confer dramatic improvements to the function of the enzymes.
It remains to raise the temperature to one more conducive to enzyme activity, 72[degrees]C, (extension; D) and allow the polymerases
to act on their substrates, extending the 3' end of each primer in a template-directed fashion toward the opposing primer's sequence.
