General description

JumpStart™ Taq DNA polymerase is a combination of Sigma′s high-performance Taq DNA Polymerase and JumpStart Taq antibody. The Taq DNA Polymerase activity is inactivated by combining the enzyme with JumpStart Taq antibody, a neutralizing monoclonal antibody to Taq DNA polymerase. Antibody inactivation provides a simple, efficient procedure for hot-start PCR. During PCR, JumpStart Taq DNA polymerase is inactive at low (room) temperature, as the temperature is raised above 70 °C in the first denaturation step of the cycling process, the complex dissociates, and the polymerase becomes fully active.

Application

JumpStart™ Taq DNA Polymerase has been used:
  • in the amplification of DNA libraries of varying sizes
  • in a methylation-specific, quantitative real-time polymerase chain reaction (MS-qPCR) to determine the BRCA1 promoter methylation status
  • in the generation of plasmid by amplifying the full-length of HIF1β via PCR
  • For PCR amplifications that require reduced non-specific amplification
  • For multiplex PCR
  • For reduction of primer dimers

Features and Benefits

  • Reduces non-specific amplification
  • Increases PCR specificity and yield
  • Reduces set-up time concerns associated with manual or wax Hot Start methods
  • Activation time of less than 1 minute

Packaging

JumpStart Taq DNA Polymerase is provided with a 10× reaction buffer available with and without MgCl2. The magnesium free 10× buffer also includes a separate tube of 25 mM MgCl2 for optimization.
Supplied with 10× reaction buffer containing 15 mM MgCl2

Other Notes

Sigma′s JumpStart Taq DNA Polymerase is an antibody-inactivated hot-start enzyme designed to minimize non-specific amplification while increasing target yield. Once the reaction temperature reaches 70°C, Taq DNA polymerase activity is restored and the resulting PCR exhibits a higher specificity and yield. This antibody-enzyme complex allows for easy and convenient set-up with less contamination risk than manual hot-start techniques. The enzyme may also be included in the master mix preparation resulting in more consistency from one reaction to the next.
