WebWith emission values ranging from 566 to 705 nm, Quasar dyes increase fluorophore choices and help eliminate potential cross-talk problems associated with multiplex qPCR and are efficiently quenched by BHQs. LGC, Biosearch Technologies' series of Quasar dyes are direct, cost-effective replacements for the Cy™3, Cy5 and Cy5.5 dyes. WebNov 4, 2024 · A fluorophore is attached to the 5’ end of the probe and a quencher to the 3’ end. If no amplicon complementary to the probe is present, the probe remains intact and low fluores- cence is detected. If the PCR results in a complementary target, the probe binds to it during each annealing step of the PCR.
