<p>Antigens are provided which induce relatively large titers of antibodies. These antigens, which may comprise certain strains of microorganisms or a plant extract, can be conjugated to a second antigen by means of an organic coupling agent. The primary antigens of the invention, when chemically coupled to a secondary antigen function as immunostimulant adjuvants. When tumor cells are the secondary antigens, a means for immunotherapeutic treatment of cancer is provided.</p> |
