The present invention provides stabilized chemiluminescent formulations for use in in vitro diagnostics, including competitive as well as sandwich-type immunological assays. The stabilized assay system may be composed of two components, where the first component may contain a chemiluminescent organic compound, an enhancer, a homogenizing agent, and a suitable buffer with formulations having a pH range from about 7.2 to about 12, and optionally a solubilizing agent. The chemiluminescent system of the present invention is useful in immunoenzymatic analytical procedures, such as immunometric, competitive binding and sandwich type assays. In such immunoassays employing the chemiluminescent system of the present invention, the detectable light signal shows a proportional decay with time in the test samples and standards, so that the decay of the light emitted does not effect the concentration of the analyte measured over the entire analyte measurement range of the immunoassay. This allows accurate measurement of analyte concentrations in a test sample over extended periods of time.
