Immunization of BALB/c mice with immunoaffinity-purified bovine or human Ro (SS-A) induces the production of antibodies reactive with Ro (SS-A). Fusion of spleen cells from the hyperimmunized mice to SP2/0 cells resulted in hybridoma cell lines that produced anti-Ro (SS-A) antibodies. Anti-Ro (SS-A) binding was established by solid-phase immunosorbent assay, immunoblotting, or RNA immunoprecipitation. Most of the anti-Ro (SS-A) antibodies bound to both human and bovine Ro (SS-A) in the solid phase, but only one of the monoclonal antibodies selectively bound to human Ro (SS-A); this suggests that there are species differences between the bovine and human Ro (SS-A) antigens. Indirect immunofluorescence studies demonstrated that most anti-Ro (SS-A) antibodies bound to cytoplasmic or nuclear HEp-2 cellular antigens, whereas others did not bind to fixed HEp-2 tissue culture cells. Nuclear staining of mouse substrates by one of the sera containing anti-Ro (SS-A) demonstrated that autoantibodies were induced by immunization with human Ro (SS-A).

UI	MeSH Term	Description	Entries
D007114	Immunization	Deliberate stimulation of the host's immune response. ACTIVE IMMUNIZATION involves administration of ANTIGENS or IMMUNOLOGIC ADJUVANTS. PASSIVE IMMUNIZATION involves administration of IMMUNE SERA or LYMPHOCYTES or their extracts (e.g., transfer factor, immune RNA) or transplantation of immunocompetent cell producing tissue (thymus or bone marrow).

D008180	Lupus Erythematosus, Systemic	A chronic, relapsing, inflammatory, and often febrile multisystemic disorder of connective tissue, characterized principally by involvement of the skin, joints, kidneys, and serosal membranes. It is of unknown etiology, but is thought to represent a failure of the regulatory mechanisms of the autoimmune system. The disease is marked by a wide range of system dysfunctions, an elevated erythrocyte sedimentation rate, and the formation of LE cells in the blood or bone marrow.

D006825	Hybridomas	Cells artificially created by fusion of activated lymphocytes with neoplastic cells. The resulting hybrid cells are cloned and produce pure MONOCLONAL ANTIBODIES or T-cell products, identical to those produced by the immunologically competent parent cell.	Hybridoma
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
