General description

JumpStart™ AccuTaq™ LA DNA Polymerase is a combination of Sigma′s high-fidelity blend, AccuTaq long and accurate (LA) DNA Polymerase, and the Taq neutralizing JumpStart Taq antibody. This specially formulated enzyme is the best choice for long-distance and high-fidelity PCR, multiplex PCR, and PCR amplification of targets with variable lengths, such as amplification of cDNA libraries. JumpStart Taq antibody reversibly binds to the AccuTaq LA DNA Polymerase, inactivating it at room temperature. The increased temperature of the first denaturation cycle causes the complex to dissociate, restoring the enzyme activity. This hot-start mechanism provides increased specificity and higher target yield in comparison to standard amplification.

Application

JumpStart™ AccuTaq™ LA DNA Polymerase has been used:
  • in polymerase chain reaction (PCR) for the amplification of soil DNA samples
  • in accurate long range PCR of histone H2A.Z in bacterial artificial chromosome (BACs)
  • as a component of the PCR reaction mix for amplification of viral DNA through conventional PCR

Features and Benefits

  • JumpStart AccuTaq LA DNA polymerase, an antibody inactivated hot start enzyme, is designed to minimize non-specific amplification while increasing target yield & specificity
  • Up to 6.5× greater fidelity in comparison to Taq DNA polymerase making it the enzyme of choice for multiplex PCR
  • Produce amplicons up to 22 kb with genomic templates and up to 40 kb with less complex templates such as lambda or bacterial genomic DNA
  • Reduce set-up time and eliminate concerns associated with manual or wax hot-start methods

Packaging

Supplied with 10× reaction buffer.

Unit Definition

One unit incorporates 10 nmol of total dNTPs into acid-precipitable DNA in 30 min. at 74 °C.

Long and Accurate PCR

Long and accurate PCR applications address the needs for longer read lengths, greater fidelity and higher yields than that which can be achieved with Taq DNA polymerase.

Hot Start PCR

The purpose of Hot Start PCR is to inhibit the PCR reaction in order to reduce nonspecific amplification, prevent the formation of primer dimers, and increase product yields.

Protocols

End Point PCR Protocol for Long and Accurate DNA Amplification

Protocol for high fidelity amplification of long PCR fragments up to 22kb from complex DNA mixtures and up to 40kb from simple DNA mixtures.
