MULTI-AMPLITUDE MODULAR LABELED COMPOUNDS

Abstract:

Sets of compounds bearing detectably different groups of labels are provided. Typically, different compounds bear different numbers of a single type of label and are thus distinguishable by the amplitude of signal produced by the label. The compounds are assembled from label components and protein cores to facilitate modular production of the compounds. In compounds containing two or more proteins, the proteins are typically covalently linked. Useful sets of compounds include sets of labeled nucleotide analogs, particularly dye-label nucleotide analogs that include tetravalent biotin-binding protein cores.
