Immunohistologic techniques in surgical pathology - a spectrum of "new" special stains.

Immunoperoxidase techniques, applied to fixed paraffin sections, provide a wide range of highly specific special stains of value to the surgical pathologist in diagnostic practice and in investigative studies. The application of "immunostains" provides an independent method of cell identification against which traditional subjective morphologic criteria may be compared: histopathology may thereby be transformed from something of an art to more of a science.
