Abstract

This paper describes the production of a panel of monoclonal antibodies (mAbs) identifying the four recognised equine IgG subisotypes IgG, IgGa, IgGb, IgGc and IgG(T). Pure preparations of the subisotypes for use in immunisations and testing were produced using a combination of gel filtration, salt precipitation, ion exchange chromatography and protein A and Protein G affinity chromatography. The specificity of mAbs for the IgG subisotypes was confirmed using ELISA assays, by characterisation of affinity purified proteins recognised by the mAbs, and by Western blotting of equine serum proteins. The expression of equine IgG subisotypes by B cells was examined by flow cytometry using the panel of mAbs.
