Abstract
A suspension of particles such as carboxylated polystyrene latex particles are coated (as by carbodiimide coupling) with an antigen (such as chemically modified Bovine Serum Albumin). The antigen-coated particles are incubated with a gamma-globulin to the antigen (such as can be produced by immunizing rabbits) under non-agglutinating conditions. The particles having antigen/gamma-globulin immune complexes are recovered and resuspended to form a diagnostic reagent which agglutinates when mixed with human serum containing Rheumatoid Factor.
