ABSTRACT:
Endogenous and exogenous proteins, and fragments thereof, are chemically modified outside the body of an animal so that when injected into the animal they produce more antibodies against the unmodified protein than would injection of the unmodified protein or fragment alone. The chemical modification may be accomplished by attaching the proteins or fragments to carriers such as, for example, bacterial toxoids. The chemical modification can also be accomplished by polymerization of protein fragments. Proteins which can be modified include Follicle Stimulating Hormone and Human Chorionic Gonadotropin. The modified polypeptide may be administered to animals for the purpose of contraception, abortion or treatment of hormone-related disease states and disease disorders, treatment of hormone-associated carcinomas, and to boost the animals' resistance to exogenous proteins, for example viral proteins.
