WebQuenchers Quenching molecules are typically placed at the 3' end of single molecule probes such as Dual-Labeled Probes, Molecular Beacons and Scorpions Probes. … WebNonfluorescent quencher (NFQ) maximizes sensitivity TaqMan MGB probes incorporate an NFQ to absorb (quench) signal from the fluorescent dye label at the other end of the probe. The properties of the NFQ combined with the short length of the MGB probe result in lower background signal than with non-MGB NFQ probes.
