THREE-DIMENSIONAL COMPLEXES BASED ON STREPTAVIDINE (OR AVIDINE) AND POLYBIOTINYLUM LUMINESCENT COMPOUNDS

摘要

The invention concerns three-dimensional complexes consisting of at least one molecule of streptavidin (or avidin) linked by an affinity bond to at least one polybiotinylated luminescent compound or to at least one polybiotinylated macromolecule coupled to at least one luminescent compound, one of the sites of the affinity bond between the streptavidin (avidin) and the biotin being free. Application: labels for immunological doses or for the detection or determination of target nucleic acids.
