ABSTRACT:
A process for the immunoassay of antigens in a biological sample wherein an element comprised of particulate supported antibody loosely encapsulated and confined within a porous filter membrane material is utilized for addition to the biological sample. The method is particularly applicable to the radioimmunoassay (RIA), enzyme-linked immunoassay (ELIA) and fluorescent immunoassay (FIA) techniques for determining the presence and concentration of minute amounts or protein antigens in biological fluid samples, and for performing multiple assays utilizing these methods.
