Abstract

Quantitative analysis of DNA products derived from polymerase chain reaction (PCR)-based assays depends on the careful optimization of each of the reaction parameters to achieve highly efficient amplification of target sequences. In practice, however, measurement of the accumulated PCR product is reliable only when analyses are performed at points in the exponential phase of the PCR amplification curve and before the onset of the plateau phase. The recent development of more sensitive DNA product detection systems has permitted the analysis of PCR assays after fewer amplification cycles, where the accumulation of product approaches linearity, while at the same time maintaining superior assay specificity. These methods include the use of high performance liquid chromatography, automated fluorescence detection, electrochemiluminescence, and the ligase chain reaction. Clinical applications of these methods are numerous and include diagnostic testing as well as therapeutic monitoring for neoplastic, infectious, and inherited genetic disease.
