Fluorescent dye and quencher

WebWhen fluorogenic dual-labeled probes were first introduced, quenchers were often a second reporter dye, typically TAMRA. The sensitivity of these probes, such as FAM-TAMRA, is limited because the fluorescence from … Traditional dark quenchers absorb broadly and emit the absorbed energy as heat and not light, which allows use of multiple reporter dyes with the same quencher (Figure 2). This characteristic allows for expanded options for multiplex assays. Dark quenchers reduce signal cross-talk, making them compatible with … See more Selecting an appropriate reporter dye for qPCR analysis will depend on the type of instrument you are using and the compatibility of the dye with the instrument. Refer to your instrument manufacturer's … See more For multiplexing applications, each target must be identified by a separate reporter dye. Select reporter dyes with the least amount of spectral overlap. Figure 2 provides the … See more
