Abstract

A non-enzymatic method of immunohistochemical staining uses a bound electron transfer agent to achieve amplification of antibody binding to specific antigens of interest in a histology or cytology specimen. A preferred embodiment uses a bound phenazine, which is reduced with a soluble reducing agent, and which in turn reduces a tetrazolium salt, to precipitate a formazan dye at the site of primary antibody binding to the antigen of interest. Reagents and kits for use in the method are also provided.
