| General description: | 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 polymerase chain reaction (PCR). Hot start PCR can significantly improve the results of DNA amplification by reducing the generation of nonspecific amplification products and primer-dimer artifacts. When used in PCR, JumpStart Taq DNA polymerase is inactive at low (room) temperature. When 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. |

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