Solid-pse radioimmunoassay of protein biosynthesis

Solid-phase radioimmunoassay was used for measuring the rate of radioisotope incorporation into a single protein species. Radioactive antigen was measured by its binding to specific antiserum covalently linked to insoluble bromoacetylcellulose. The insoluble antigen-antibody complex was collected on filters for counting. The assay is performed in about 4 hours as compared with several days for methods based on the precipitin reaction.
