N2 - Monoclonal antibodies were produced against serum-derived bovine immunoglobulin E (IgE). Culture supernatants of hybridomas were initially screened by enzyme-linked immunosorbent assay (ELISA). Supernatant-derived antibodies were concentrated and further characterized using ELISA, reverse cutaneous anaphylaxis, immunohistochemical staining, and immunoblotting of IgE-containing samples separated by SDS-polyacrylamide gel electrophoresis (PAGE). Eight monoclonal antibodies showed specificity for bovine epsilon immunoglobulin heavy chain. Two antibodies (E2 and E32) reacted in immunoblots of SDS-PAGE of serum IgE under reducing conditions. Additionally, E2, E5, and E32 detected epsilon chain in serum separated by SDS-PAGE and then renatured. Antigen-specific IgE was detected in Western blots by E5 and E32. Immunoperoxidase staining of IgE-containing cells in mesenteric lymph node sections was detected with E5, E21 and E32. All eight antibodies produced positive reverse cutaneous anaphylaxis reactions in calf skin. All functioned well in ELISA as a plate-sensitizing reagent for quantitation of total IgE; E5 and E32 worked well as a primary antibody in antigen-specific IgE assays. These antibodies will be useful in research applications and in diagnostic assays.
