Enzyme-Linked Immunosorbent Assay (ELISA) for Metallothionein
A heterogeneous, double-antibody, fluorometric enzyme-linked immunosorbent assay (ELISA) is described for the detection and quantitation of metallothionein (MT). The protocol uses the same immunological reagents as the radioimmunoassay (RIA) developed previously in this Laboratory; fluorescence replaces radioactivity for detection of the reference antigen in the specific binding reaction. Present results indicate that the developed ELISA has approximately the same range of capability in detecting and quantitating MT as is characteristic of the RIA. The ELISA has the advantage that the time required to perform a typical assay is significantly less than that required for the RIA.
