The immunogenic properties of the soluble complexes of bovine serum albumin (BSA) and synthetic polyelectrolytes were studied. The polyelectrolytes used in these complexes were 4-vinyl-N-ethylpyridinium bromide and 4-vinyl-N-cetylpyridinium bromide (complex I), 4-vinylpyridine and 4-vinyl-N-acetylpyridinium bromide (complex II). C57BL mice were immunized with different doses of BSA, complexes I and II introduced intraperitoneally in a single injection, and the number of plaque-forming cells (PFC) in the spleen was determined by modified Jerne's test with the use of BSA-covered sheep red blood cells. The above complexes were shown to stimulate the production of PFC against BSA 50-100 times more intensively than pure BSA. The mixtures of BSA with the above-mentioned polyelectrolytes stimulated PFC production to a considerably lesser extent. Thus, the polymeric part of these conjugates was not an antigen, but served as a carrier inducing pronounced immune response to the antigenic (protein) part of the complex.¿¿¿¿¿¿¿¿¿¿¿¿¿¿¿¿¿¿¿¿¿¿¿¿¿¿¿¿¿¿
