Designing an RQ Experiment<br />

• Select the PCR method<br />

(multiplex or singleplex).<br />

• Designate the targets, calibrator,<br />

endogenous control, and replicates.<br />

• Select the SDS chemistry and<br />

reagent configuration.<br />

• Choose the primers and probes.<br />

Traditional PCR is performed as a singleplex reaction, where a single primer pair is<br />

present in the reaction tube or well. Only one target sequence or endogenous control can<br />

be amplified per reaction—target sequences and endogenous controls cannot be<br />

amplified in the same tube.<br />

In multiplex PCR, two or more primer pairs are present in the reaction. Each primer pair<br />

amplifies either a target sequence or an endogenous control. The availability of multiple<br />

reporter dyes for TaqMan ® probes, each with different emission wavelength maxima,<br />

makes multiplex PCR possible.<br />
