Fluorescent immunoassay employing a phycobiliprotein labeled ligand or receptor

摘要

Sensitive detection techniques and compositions for such techniques employing fluorescent proteins having bilin prosthetic groups as labels i.e. phycobiliprotein. The bilin containing proteins can be conjugated to ligands or receptors for use in systems involving ligand-receptor binding for the analysis, detection or separation of ligands and receptors. Particularly, one or more of the bilin containing proteins may be used as labels in conjuction with each other or other fluorescers for defining subsets of naturally occurring aggregations e.g. cells.
