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.

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
