A method to rapidly perform immunofluorescence or light microscopic staining on formalin-fixed paraffin sections has been devised utilizing magnetic albumin microspheres containing Staphylococcal protein A. Because the protein A constituent of the microspheres has the property of binding the Fc portion of immunoglobulin G (IgG) class antibodies, the microspheres can be used to rapidly bind antigen-antibody complexes by the Fc portion of the antibody. Deparaffinized sections were stained with fluorescein isothiocyanate-conjugated antibody (IgG fractions) by standard techniques, after which the protein A microspheres were layered over the sections. Distinct fluorescence of sections was noted with the addition of the microspheres, whereas only autofluorescence was present with direct staining alone. The microspheres were also visualized by light microscopy by a subsequent Prussian blue reaction, staining the Fe3O4 within the microsphere matrix. This method represents a more rapid method for identifying antigens in tissues embedded in paraffin than has previously been reported.
