عنوان انگلیسی PRODUCTION OF MONOCLONAL ANTIBODY AGAINST HUMAN IMMUNOGLOBULIN
چکیده انگلیسی مقاله Immunoglobulin E is one of the five classes of immonoglobulins that plays an important role in allergic diseases. Production of monoclonal antibodies by a single clonotype against different epitopes of immunoglobulin E has high priority in development of diagnostic kits. In this study, an attempt was made to produce monoclonal antibodies against human immunoglobulin E. Balb/c mice were immunized with semipurified immunoglobulin E and spleen cells fused with SP2.0 mouse myeloma eel! line in the presence of polyethylene glycol. Supernatant of hybridoma cells was screened for detection of antibody by enzyme linked immonosorbent assay method. Cloning of selective high absorbance wells were done with limiting dilution method. The suitable clone (monoclone) was selected by enzyme linked immunosorbent assay and confirmed by immunoblot. The subclass of the chosen monoclonal antibodies was determined and the clones freezed and kept in liquid nitrogen. During this study three successful fusions were carried out, which resulted in development of 156 clones with high production of anti-IgE. Fourteen clones with the highest titres were selected for cloning. After limiting dilution more than 100 monoclonal antibodies were produced and the suitable (me (GJ0F7), i.e.; the clone which displayed the high absorbance in reaction with purified immunoglobulin E and the lowest cross-reactivity with immunoglobulin M, immunoglobulin G and immoglobulin A was chosen. In immunoblotting, presence of high density band in reaction with immunoglobulin E was confirmed. The suitable mab was shown to be IgG 1 subclass with kappa light chain. It seems that, this mab could be successfully used in diagnostic kits.
