Effect of water-soluble adjuvants on in vitro lymphocyte immunization

Water-soluble adjuvants prepared from Mycobacteriim smegmatis and human mixed mycobacteria strains C, DT, and PN were found to increase lymphocyte response in one-way mixed-lymphocyte culture and in vitro immunization to cultured human tumor cells. Phytohemagglutinin-induced lymphocyte blastogenesis, however, was depressed by water-soluable adjuvants.
