A real-time polymerase chain reaction (RT-PCR), also known as quantitative polymerase chain reaction (qPCR), is a laboratory technique of molecular biology based on the polymerase chain reaction (PCR). It monitors the amplification of a targeted DNA molecule during the PCR, i.e. in real-time, and not at its end, as in conventional PCR. Real-time PCR can be used quantitatively (quantitative real-time PCR), and semi-quantitatively, i.e. above/below a certain amount of DNA molecules (semi quantitative real-time PCR).
Two common methods for the detection of PCR products in real-time PCR are: (1) non-specific fluorescent dyes that intercalate with any double-stranded DNA, and (2) sequence-specific DNA probes consisting of oligonucleotides that are labelled with a fluorescent reporter which permits detection only after hybridization of the probe with its complementary sequence.
Fluidigm's revolutionary integrated fluidic circuits (IFCs) and BiomarkHD empower life science research by automating PCR reactions in nanoliter volumes. This means using less sample and reagent, and a single microfluidic device, to achieve the high-quality, consistent results your work depends on. The Biomark HD system can run IFCs in real-time read modes, bringing flexible, efficient and economical PCR solutions to a range of applications. In addition, multiple assay chemistries and different sample/assay configurations are supported.
