by immunizing mice with killed whole bacterial cells of brucella abortus s (99), a panel of six hybridomas producing monoclonal antibodies (mab) specific for the surface antigens of this bacterium were produced. elisa was used to screen the hybridoma supernatants. immunoblots of the cell extract indicated that three mab were specific for s-lps (ba-1, ba-2, ba-3) and three others were reactive w...

despite the major advances in conventional forms of treatment (i.e. surgical techniques, radiotherapy and chemotherapy) and improved survival rates, cancer is still the second leading cause of death in developing countries. one major limitation of cytotoxic drugs and radiation in the treatment of cancer patients is their inability to discriminate between malignant and normal tissues. this in tu...

background : production of monoclonal antibodies to leishmania antigens assists the identification and characterization of these organisms. objective: production of monoclonal antibodies against epitopes on the gp63. methods: two murine monoclonal antibodies to gp63 were produced and characterized. the reactions of both antibodies with soluble leishmanial antigens, purified gp63 and truncated r...

Background: Sjögren’s syndrome is the second most common systemic autoimmune disease after rheumatoid arthritis, RA, with a prevalence of about 0.5% in the general population. It occurs primarily in perimenopausal women (at a ratio of women to men of 9: 1) Sjögren’s syndrome is characterized by lymphocytic infiltration to exocrine glands. The specific autoantibodies of this syndrome are against...

Multiple Myeloma is a neoplasm of B cell lineage characterized by excessive proliferation of abnormal plasma cells. It is characterized by a clinical  pentad of 1) anemia, 2) a monoclonal protein in the serum or the urine or both, 3) bone leisons and or bone pain, 4) hypercalcemia >11.5g/dl and 5) renal insufficiency. Non secretory multiple myeloma is a rare variant of the classic form of multi...

Plasma cell dyscrasias are a group of entities characterized by neoplastic proliferation single clone plasma cells, typically producing monoclonal Immunoglobulin [1].
