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
- For PCR amplifications that require reduced non-specific amplification
- For multiplex PCR
- For reduction of primer dimers
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
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
One unit incorporates 10 nmol of total dNTPs into acid-precipitable DNA in 30 min at 74 °C.
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.
