title: Microplate solid-phase radioimmunoassay for rat prolactin.
abstract: A rat prolactin solid-phase radioimmunoassay has been developed that uses 96-well microtiter plates with removable wells to which the antibody is firmly adsorbed, resulting in a solid-phase antibody. Antigen as either reference or unknown competes with radioactivity labeled antigen for binding sites on the solid-phase antibody. After immunoreaction, free antigen is removed by washing the wells with phosphosaline solution. The solid-phase antibody-antigen complex is counted for quantitation with data reduction methods currently used in routine radioimmunoassay procedures. This microplate solid-phase radioimmunoassay has several advantages over conventional methods without sacrificing specificity, sensitivity, or accuracy. This method is rapid, compact, economical, easily automated, and could be readily established in other laboratories.
