Immune complexes (IC) isolated from pleural effusions of lymphomas with favorable and unfavorable prognoses were of IgG type. These IC were further dissociated by ion exchange chromatography using 8 M urea. The antibody was found to be a high molecular weight protein (1.5×105 daltons) and reacted with antihuman IgG immunologically while a second peak obtained on ion exchange chromatography may be an antigen moiety with a molecular weight of 3.2×104 daltons as it reacted immunologically with the antibody. Strong cytoplasmic fluorescence was observed with various cell suspensions of lymphomas when reacted with the antibody preparations. The antisera raised against two different antigen fractions prepared from two lymphomas — nHL and LL showed positive fluorescence with both nHL and LL suspensions. The absorption of these rabbit antibodies with individual cell extracts or with antigen preparations also entirely blocked the cytoplasmic staining. The antigen moiety (PK-II) may have a common origin in the disease process. Pleural effusions from patients with unfavorable and favorable prognoses showed identical patterns of separation of IC components. |
