| Abstract: | Human monoclonal antibodies were tested using different immunochemical procedures for their reactivity with various antigens. The great majority of human monoclonal IgM antibodies (15 out of 24) turned out to bind to a whole series of recognized antigens (DNA, keratin, tetanus toxin, ricin etc.). The specificity of these reactions was detected by competitive assays. For some antibodies a simultaneous reaction with two antigens could be demonstrated by capture bridge technique. IgG antibodies also turned out to be multireactive, but not to the same extent (range of antigens much smaller, only 5-6 out of 53). |
