title: [The isolation of monoclonal antibodies to Cryptococcus neoformans antigens].
abstract: In this work conditions for the reproduction of hybridoma technology, specially adapted to C. neoformans, for obtaining monoclonal hybridomas (McAb) to diagnostically significant antigens of C. neoformans, the infective agent of cryptococcosis, are presented. The advantages of using the short-time cycle of stimulation of mouse B lymphocytes with low doses of C. neoformans capsular polysaccharide and the effectiveness of the hybridization of mouse spleen cells with myeloma cells, line Sp2/0, are shown. Four lines of stable hybridomas, producing McAb to different epitopes of C. neoformans surface antigens, have been obtained. The specific activity of McAb has been studied in the indirect immunofluorescence assay, the cytochemical and solid-phase enzyme immunoassays (EIA). McAb 3E2, Cr2 and 2G9 have been shown to be suitable for use in diagnostic EIA systems.
