Abstract: The present invention provides an improved assay for measuring thyroxine uptake by thyroxine binding globulin in which thyroxine binding globulin (TBG) activity is measured directly. The method comprises combining a sample in an aqueous solution with an enzyme donor (ED) conjugated to an analogue of polyiodothyronine that competes with thyroxine for thyroxine binding globulin binding sites. An enzyme acceptor (EA) characterized by providing a modulated enzyme activity in relation to the amount of TBG activity is combined with an enzyme donor and sample in an aqueous solution. The amount of enzyme activity in comparison to a control solution having a known amount of available TBG binding sites is determined.

Abstract: The present invention provides reagents for a detectable label for use in specific binding assays. Specifically, modified .beta.-galactosidase enzyme donors (ED) and acceptors (EA) are utilized. Both ED and EA are modified to form separate ED and EA complexes by coupling each with a linking element and a binding moiety which is specific to a binding site in the analyte. The ED and EA complexes are incapable of forming active enzyme in the absence of the analyte. However, when analyte is present, ED and EA complexes which bind to a common analyte in a sample, active .beta.-galactosidase is formed.
