摘要
Substantially pure antigenic surface proteins of Anaplasma marginale have been identified, and are capable of inducing immune responses in ruminants which neutralizes virulent Anaplasma marginale. The antigenic surface proteins have one or more components having a molecular weight of about 105,000 daltons, 86,000 daltons, 61,000 daltons, 36,000 daltons, 31,000 daltons, or 15,000 daltons, and can be purified by an immunoaffinity chromatography process comprising the steps of disrupting Anaplasma marginale initial bodies by treatment with a detergent, passing the disrupted initial bodies over a chromatography column comprising an insoluble matrix coupled to monoclonal antibodies against a determinant on said antigenic surface protein to selectively bind said antigenic surface protein to said monoclonal antibodies and recovering the bound substantially pure antigenic surface protein from said insoluble matrix. The antigens have further utility in diagnostic tests for anaplasmosis. They can be synthesized by polypeptide procedures or by genetic engineering.
