Using the latest in QuantStudio instrumentation, Kashi Clinical Laboratories provides accurate measurements of nucleic acid concentrations using quantitative polymerase chain reaction (qPCR) in real time. The quantitative measurement is collected during the log phase of PCR amplification, when the quantity of PCR product is directly proportional to the amount of template nucleic acid. With qPCR's high dynamic range, we can provide detection down to a two-fold change in concentration or quantitation of RNA from a single cell.
A quantitative real-time polymerase chain reaction is a laboratory technique of molecular biology based on the polymerase chain reaction (PCR), which is used to amplify and simultaneously quantify a targeted DNA/RNA molecule. For one or more specific sequences in a DNA/RNA sample, quantitative PCR enables both detection and quantification. The quantity can be either a concrete number of copies (absolute quantitation) or a relative change in DNA/RNA concentration when normalized to DNA input or additional normalizing genes (relative quantitation).
The procedure follows the general principle of polymerase chain reaction. Its key feature is that the amplified DNA is detected as the reaction progresses in "real time." This is a more precise approach compared to standard PCR, where the product of the reaction is detected at its end.
