Ct mean in qpcr
WebQuantitative polymerase chain reaction (or qPCR) is a well-established assay for nucleic acid quantification and is still regarded as the method of choice in most areas of molecular biology. WebCt = PCR cycle A typical qPCR run has around 40 cycles. The Ct is the value where the PCR curve crosses the threshold, in the linear part of the curve. It’s the value that will be …
