Note: The use of DMSO or formamide with JumpStart REDTaq DNA Polymerase is not recommended due to interference with the enzyme-antibody complex. Other co-solvents, solutes (e.g., salts) and extremes in pH or other reaction conditions may reduce the affinity of the JumpStart Taq antibody for the Taq DNA polymerase and thereby compromise its effectiveness.
Because Taq DNA polymerase is a magnesium ion-dependent enzyme, the optimal conditions for the concentration of Taq, template DNA, primers, and MgCl2 will depend on the system being utilized. It may be necessary to determine the optimal conditions for each individual component. This is especially true for JumpStart REDTaq, cycling parameters, and the MgCl2 concentration. It is recommended the enzyme and the MgCl2 be titrated to determine the optimal efficiency.
To minimize tube-to-tube variation, preparation of a PCR master mix with JumpStart REDTaq DNA Polymerase is recommended. The amount prepared should be based on the number of PCR reactions to be performed.
1. Add the following reagents to a 0.2 mL or 0.5 mL PCR tube.
2. Mix gently and briefly centrifuge to collect all solution at the bottom of the tube.
3. Add 50 µL of mineral oil to the top of each tube to prevent evaporation (optional, depending on model of thermal cycler).
4. Amplification parameters will vary depending on the primers and the thermal cycler used. It may be necessary to optimize the system for individual primers, template, and thermal cycler.
Typical cycling parameters:
5. The amplified DNA can be evaluated by loading 5-10 µL of the PCR reaction directly onto agarose gel. It is not necessary to add a separate loading buffer/tracking dye.
Note: A minimum of 1.5 units of JumpStart REDTaq DNA polymerase must be added per 50 µ reaction to ensure enough glycerol is present for direct gel loading. The red tracer comigrates with 125 bp fragment in a 1% agarose gel.
