    Abstract: Method and composition for detecting one or more selected polynucleotide regions in a target polynucleotide. In the method, a mixture of sequence-specific probes are reacted with the target polynucleotide under hybridization conditions, and the hybridized probes are treated to selectively modify those probes which are bound to the target polynucleotide in a base-specific manner. The resulting labeled probes include a polymer chain which imparts to each different-sequence probe, a distinctive ratio of charge/translational frictional drag, and a detectable label. The labeled probes are fractionated by electrophoresis in a non-sieving matrix, and the presence of one or more selected sequences in the target polynucleotide are detected according to the observed electrophoretic migration rates of the labeled probes in a non-sieving medium.

    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. This can be accomplished by linking together, into a single molecule, two or more identical quenchers, by reacting the quenchers with a multivalent linker. The structure of the multi-chromophoric quencher can also be varied to quench a broader range of reporter emission wavelengths than previously possible. This can be accomplished by linking together, into a single molecule, two or more different quenchers, by reacting the quenchers with a multivalent linker. The structure of the multi-chromophoric quencher can also be varied to simultaneously broaden the absorption range and increase the total absorption within the absorption range. This can be done by combining the two concepts described above. In other words, 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.
