HS Probe qPCR Mix
For research use only
2× HS Probe qPCR Mix
1 ml × 5
1 ml × 5
This reagent can be stored for 2 months at 4°C. For longer storage, it should be kept at -20°C.
HS Probe qPCR Mix is designed for high-performance, high-throughput real-time PCR using sequence-specific fluorogenic probes. 2× HS Probe qPCR Mix contains the components (except primers, DNA template and probe) that necessary to perform PCR. The core component of the mix is OptimusTM Hotstart Taq DNA Polymerase, a hot-start polymerase with chemical modification, which brings high specificity by reducing non-specific products as the enzyme activity is temperature-dependent and is inhibited at room temperature. Combined with well-optimized buffer can significantly improve amplification efficiency. This product is perfectly compatible with common quantitative PCR instruments, such as ABI, Roche, Bio-Rad, etc.

1. Preparation of reaction solution
Add the following reagents to the proper thermal cycler reaction tube or plate on ice:
2× HS Probe qPCR Mix
Forward Primer (10μM)
Reverse Primer (10μM)
to 20 μl
? Prepare according to the recommended volume of each instrument.
? The optimal range for primers is 0.1~1.0 μM. In general, the primers with a final concentration of 0.2 μM work well.
? The concentration of the probe used is related to the Real Time PCR amplification instrument, probe species and types of fluorescent label. Please refer to the instructions when using it. Typically, the final concentration is between 0.1 and 0.5 μM.
? Use 1-10ng cDNA or 10-100ng gDNA for each reaction of 20 μl system.
? Users can increase the amount of the the qPCR Mix when using low-copy gene as template.
2. Setup the plate
Transfer the reaction mixture to PCR tubes/plates. Reaction volumes can be reduced to 10 μl if the instrument supports a low volume system.
Cap or seal the reaction tubes/plates then centrifuge briefly to spin down the contents and eliminate any air bubbles.
3. Preform qPCR using the following thermal cycling condition
Set the thermal cycling conditions using default PCR thermal cycling conditions specified in the following tables according to the instrument cycling parameters of the specific primers.
Standard 3-step PCR mode:
*The instrument do signal acquisition at this stage. The usual annealing temperature is 55-65 oC. The annealing temperature is generally set to Tm-5 oC of the primer used, generally not less than 55 oC. (melting temperature, Tm). Set the time of annealing according to the instrument guide.
2-step PCR mode:
Annealing & Extension*
*The instrument do signal acquisition at the extension stage, and some instruments require more than 30 seconds, such as ABI 7300 for at least 31 seconds and ABI 7500 for at least 34 seconds.
If the reaction performs not well, it is recommended to adopt a 3-step amplification procedure.
4. Analyze the results
Data analysis varies depending on the instrument used. Please refer to your instrument user guide for information.
