PROCESS FOR PREPARING PROTEIN DERIVED FROM THE ENVELOPE GENE OF HUMAN IMMUNODEFICIENCY VIRUS TYPE I AND A VACCINE CONTAINING SAID PROTEIN

摘要

An Acquired Immunodeficiency Syndrome (AIDS) vaccine containing the Human Immunodeficiency Virus, Type-1 (HIV-1) envelope proteins is produced from cloned HIV-1 envelope genes in a baculovirus-inset cell vector system. The recombinant HIV-1 proteins are purified, assembled into particles and then adsorbed on an aluminum phosphate adjuvant. The resulting adsorbed recombinant HIV-1 virus envelope protein formulation is highly immunogenic in animals and elicits antibodies which bind to the HIV-1 virus envelope and neutralize the infectivity of the virus in in vitro tests.
