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. WebBlack Hole Quencher™ Two commonly used quenchers, TAMRA™ and DABYCL, limit the ultimate sensitivity and flexibility of qPCR. TAMRA is not a dark quencher and therefore contributes to an overall increase in background because of its own native fluorescence.
