Recombinant mouse/sheep IgE was used in the production of an anti-IgE monoclonal using conventional hybridoma techniques. The specificity of hybridomas secreting anti sheep IgE monoclonal antibodies was verified using a number of assays including competitive ELISAs, ability to induce mediator release from mast cells, and IgE binding using western blotting. Immunohistochemical staining demonstrated the binding of putative anti-IgE monoclonals to the sheep mast cell surface. The isotype of the antibody was IgG1:K.
