Technology Overview: SYBR Green qPCR In quantitative PCR, DNA amplification is monitored at each cycle of PCR. When the DNA is in the log linear phase of amplification, the amount of fluorescence increases above the background. The point at which the fluorescence becomes measurable is called the Quantification Cycle (C q) or crossing point.
By using a fluorescent report in the PCR reaction, this process allows you to measure DNA generation in the qPCR assay. There are two methods of qPCR: SYBR Green and probe-based. SYBR Green qPCR allows monitoring of amplification of any double-stranded DNA sequence. It does not require probes and thus reduces assay setup and running costs.
Due to the nonspecific binding of SYBR ® Green, dye-based assays are generally not used for multiplex PCR, since all products are labeled and are thus not distinguishable. As with any nonspecific dsDNA-binding molecule, SYBR ® Green can bind to primer-dimers and other nonspecific dsDNA products.
Good QPCR efficiency promotes assay reproducibility and sensitivity. Primer DesignGiven that PCR primers are a relatively cheap component of a QPCR assay, it is good practice to order and test at least 2 primer pairs for every new QPCR assay. This will maximize the chance of establishing a reliable, reproducible and sensitive assay.
