WebApplied Biosystems TaqMan TAMRA probes are dual-labeled probes used for real-time PCR applications using TaqMan chemistry. TaqMan TAMRA Probes feature a 5’ fluorescent reporter dye (FAM, VIC, or TET) and 3’ fluorescent quencher (TAMRA dye). WebThe fluorophore is attached at the 5' end of the probe and the quencher moiety is located at the 3' end. During the combined annealing/extension phase of PCR, the probe is cleaved by the 5'–3' exonuclease activity of Taq DNA polymerase, separating the fluorophore and the quencher moiety.
