Abstract
A double antibody radioimmunoassay method for determining antigens in a sample wherein polyethylene glycol is provided in a reaction medium to accelerate an immunoprecipitation reaction between water-soluble first antibodies bound to antigen and water-soluble second antibodies which are not specific to said antigens but which are specific to said first antibodies. A double antibody, multi-component radioimmunoassay test kit is also provided. The kit contains radiolabeled antigen reagent, first water-soluble antibody reagent and second water-soluble antibody reagent, as well as a polyethylene glycol reagent, which may optionally be combined with the second antibody reagent, in an amount sufficient to accelerate an immunoprecipitation reaction, between said first and second reagents.
