Description :
Hot start Taq DNA Polymerase for qPCR is designed for Real-Time PCR and Hot-start PCR. A
special inhibition the reaction at room temperature until after the first denaturation step. This prevents primerdimers
and other artefacts.
PowerAmp 2X PCRmix-Green is optimized mixture contain of Hot Start Taq enzyme, reaction buffer, dNTP,
enhancer as 2-fold concentration. PowerAmp 2X PCRmix-Green is designed to allow the user for quick ,
easy preparation of reaction mixture.The PowerAmp 2X PCRmix-Green can be amplification PCR products
up to 5 kb and the products can be directly cloning into T-vector.
Primers: Use 0.3 μM per primer as a general starting point. For larger amounts of template (e.g., 200 ng genomic
DNA), increasing the concentration up to 0.5 μM per primer may improve yield.
Annealing Temperature: The annealing temperature is slightly higher than with typical PCR. The optimal annealing
temperature should be ~2°C lower than the Tm of the primers used. A range of 58–68°C is recommended.
Extension Time: As little as 30 seconds per kb is suitable for most targets. Use up to 60 seconds per kb for
maximum yield.
PCR Protocol:
1.Thaw the 2x Hot start mix at room temperature. Vortex
the 2x Hot start mix and then spin it briefly in a micro
centrifuge to collect the material in the bottom of the tube.
2. Prepare one of the following reaction mixes on ice:
Component | Volume |
2x Hotstart mix | 12.5 ul |
Primer1 (20 pmol) | 1-2 ul |
Primer2 (20 pmol) | 1-2 ul |
template | 1-5 ul |
ddH2O | Up to 25 ul |
Total | 25 ul |
3. If necessary you can scale up your volume
Program the thermal cycler as follows
Step | Temperature | Time | Cycle |
Initial denaturation | 94-95°C | 5-10mins | 1 |
Denaturation | 94-95°C | 0.2-2mins | 20-40 |
Annealing | 50-68°C | 0.2-2mins | |
Extension | 72°C | 1min/1kb | |
Final extension | 72°C | 1-10mins | 1 |
Step
After cycling, maintain the reaction at 4°C. Samples can
be stored at –20°C until use.
Analyze products using standard agarose gel electrophoresis.
