High amplification efficiency
Wide linear range
A real-time quantitative polymerase chain reaction(qPCR) is a technique of molecular biology, that is used to amplify and simultaneously detect or quantify targeted DNA molecules. The procedure follows the general principle of PCR. During PCR reaction progress the accumulation of PCR products results in the enhancement of fluorescence signals as the cycle numbers increase. Thus PCR reaction progress is detected in "real time" by monitoring the fluorescence intensity.

Taking an example of TaqMan probe method
1. Design and synthesize primers and probes
Customers provide gene information for us, primers and probes are designed by our own algorithm of the company.
2. Perform a real-time PCR experiment
A real-time PCR is performed after RNA in the samples provided by customers is extracted and purified. The examining report is presented.
