| 摘要 |
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) and enzyme-linked immunoassay (ELIA) techniques for determining the presence and concentration of minute amounts of protein antigens in biological fluid samples, and for performing multiple assays utilizing these methods.
