title: [Modification of the viral immunoassay for determining ultramicro-quantities of antigens].
abstract: A technique for ultramicro-quantitation of antigens is suggested. It is based on the antigen isolation by immunosorption and a subsequent assay using phage-antigen conjugate (modification of viral immunoassay). Antibody Fab' fragments were bound to both the immunosorbent and the conjugate through their terminal thio groups. The technique sensitivity was one-two orders higher than that of ELISA for the corresponding antigens.
