title: Protein A-peroxidase conjugates for two-stage immunoenzyme staining of intracellular antigens in paraffin-embedded tissues.
abstract: Staphylococcal protein A conjugated to horseradish peroxidase was employed in an indirect immuno-staining technique to identify intracellular antigens in paraffin-embedded tissues. The sections were incubated with specific antisera and the antigen-IgG complexes demonstrated with protein A-peroxidase conjugate. Immunoglobulins, lysozyme and insulin were satisfactorily detected by this technique. A comparison of this method with the PAP, "labelled antigen" and peroxidase-labelled antibody sandwich techniques was made.
