A biased solid-phase radioimmunoassay for thyroxine (T4) using T4-125I presaturated antibodies
- 17 Downloads
An assay for thyroxine (T4) is demonstrated using specific antibodies covalently coupled to controlled pore glass (CPG). In this assay immobilized antibodies saturated with labeled T4 are employed in a preloaded unit tube configuration. These complexes are stable for long periods of time when stored in buffer. This concept results in a highly reproducible and sensitive assay for T4 that requires a single pipetting step.
