WebDifferences between detection using FRET probes and TaqMan probes. (a) Energy transfer in FRET probes (the e − acceptor emits fluorescence when placed close to the e − donor). (b) Energy transfer in hydrolysis probes (TaqMan) (the e − donor emits fluorescence when the distance to the acceptor or quencher is higher than 10 nm). WebThe 3’ end of all TaqMan MGB probes contains a specific binding element that binds to the minor groove of the DNA helix (MGB or minor groove binder), which improves …
Web31 mrt. 2016 · The TaqMan qPCR relies on a pair of primers and a dually labelled oligoprobe. During the reaction, the signal is emitted only after the probe hydrolysis. This requires a unique arrangement of three target sequence-specific oligonucleotides. The hydrolysis probe, therefore, introduces an additional level of specificity into the qPCR … WebProbe Master is a ready-to-use reagent mix that simplifies the preparation of reactions for qPCR and 2-step qRT- PCR.
