Immunoperoxidase techniques: practical and theoretical aspects

Abstract

Immunoperoxidase methods have much in common with established immunofluorescence procedures. Both have the potential for specific demonstration of cell and tissue antigens, with similar limitations demanding rigorous control of specificity. In any study the choice of an immunofluorescence method or an immunoperoxidase method can be made on rational grounds, according to the desired objective, the degree of morphologic detail required, the material available for study, and the ease of access to specialized ultraviolet microscopy. In this article the relative merits of the various immunoperoxidase procedures are examined, and theoretical and practical aspects governing the application of these methods are discussed in detail.
