Abstract: Dark quencher constructs, termed “multi-chromophoric quenchers” are described herein that comprise at least two dark quenching moieties, which can be the same or different, linked together by at least one multivalent linking moiety. The structure of the multi-chromophoric quenchers can be varied to selectively enhance quenching within a specific range of reporter emission wavelengths, to quench a broader range of reporter emission wavelengths than previously possible, or can combine both concepts. Multiple types of quenching moieties can be employed to increase the absorption range and a multiple number of each type of quenching moiety can be used to increase the total absorptivity within the absorption range. The multi-chromophoric quenchers can be tethered to probes for biomolecules, insoluble supports and/or fluorescent dyes for use in a wide variety of biomolecular assays.
