Multiplex quantitative polymerase chain reaction (multiplex qPCR) enables the amplification of more than one target in a single reaction using different reporter dyes with distinct fluorescent spectra. The number of reporter fluorophores is typically restricted to three or four, depending upon the capability of the real-time PCR platform and software used. Each target is amplified by a different set of primers and a uniquely labeled probe that distinguishes each PCR amplicon. Thus, the levels of several targets of interest can be quantified in real time. By combining several reactions in a single tube, multiplex qPCR reduces the quantity, and cost of reagents needed to screen a sample for multiple targets. Specificity and efficiency are not affected by the inclusion of the three assays in a multiplex reaction.
