چکیده

BACKGROUND & OBJECTIVE Monoclonal antibodies against red blood cell antigens used in research and as diagnostics in India are commercially procured from western countries. Indigenously generated potent clones are not available in India. Hence, the objective of the present study was to raise potent murine monoclonal antibodies against A, B and H blood group antigens indigenously and establish a stable clone of anti-B secreting cells. METHODS Spleen cells of female BALB/c mice immunized with B group red blood cells were fused in presence of polyethylene glycol (PEG) 1500 with a mouse myeloma cell line Sp 2/0 Ag. 14 in hypoxanthine aminopterine thymidine (HAT) selective medium and incubated at 37 degrees C, 5 per cent CO(2) and 95 per cent humidity for a week. RESULTS The culture supernatant of the wells showing anti-B activity, were further subcloned and a clone 2C4D5F10 was generated which showed a good potency, avidity and specificity. INTERPRETATION & CONCLUSION The anti-B clones thus produced indigenously provided a useful reagent in blood group typing. The unlimited availability unlike polyclonal antisera makes this reagent more cost-effective. It also ensures a regular supply with the similar specificity.

THE PRODUCTION OF MURINE MONOCLONAL ANTIBODIES (MAb) DIRECTED AGAINST HUMAN T- LYMPHOCYTE SUBSETS

The production of murine monoclonal antibody (MAb) has not yet been reported in Iran. The present work describes for the first time the generation of several murine hybridoma clones secreting MAbs directed against human leukocyte surface antigens. The secreted antibodies by hybridoma clones have been screened on different lymphoid and non-lymphoid tissues. Results indicated that of seven h...

Generation and Evaluation of Monoclonal Autoantibodies in Systemic Lupus Erythematosis

Three murine monoclonal anti-ssDNA autoantibodies have been produced by fusion of spleen cells from NZB/NZW F1 hybrid mice with Sp2/0-Ag 14 murine myeloma cells. Specificity studies characterizing monoclonal anti - ssDNA autoantibodies revealed binding patterns for nucleotides. Clone E-4-1 showed preferential binding with mono-di-and polyguanosine. Clones E-4-4 and E-11-1 specitically bound mon...

Production and Characterization of Murine Monoclonal Antibodies Recognizing Conformational and Linear Epitopes Localized on Human IgA2 Molecules

Background: There are two subclasses of human IgA (IgA1 and IgA2) that differ in antigenic properties and in chemical composition. The constant domains of α1 and α2 heavy chains have >95% sequence homology though major structural differences exist in the hinge region. Quantitation of IgA subclass levels depends on the availability of monoclonal antibodies (MAbs) specific for conserved conformat...

Background and Objectives: Rituximab is an anti-CD20 chimeric monoclonal antibody widely used for the treatment of malignant B cells lymphoma. However, the immunogenicity of murine-derived monoclonal antibodies and the large size of full length antibodies restrict cancer immunotherapy. Humanized single chain antibodies can be a solution and a promising alternative for application in immunothera...
