PCR • Polymerase Chain Reaction • http://www.dnai.org/b/index.html • http://palou.uib.es/roolpi/PCR/
Basic PCR • Initially reagents in excess, template and product don’t renature and outcompete primer binding, so amplification occurs at an exponential rate. • Timepoint when exponential turns to linear rate is different depending on the initial concentration of the target molecule.
Basic PCR • To properly quantify one product relative to another you need to be in the exponential phase of amplification for both and know when the end point occurs.
