General description

JumpStart Taq DNA Polymerase (JumpStart Taq) is an optimized blend of Sigma′s high-performance Taq DNA Polymerase and JumpStart Taq antibody.


JumpStart Taq DNA polymerase has been used:
  • In the PCR amplification of DNA isolated from herbarium specimens.
  • In the PCR reaction mixture for Randomly amplified polymorphic DNA polymerase chain reaction (RAPD PCR).
  • To amplify and detect a point mutation in the EGFR exon 19 using specific cancer cell lines.
  • In Real-time quantitative 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


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 without MgCl2. Includes a separate tube of 25 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.
