Abstract

A number of techniques have been developed to use chemical, immunological, and molecular biology assays in histological material. Collectively termed histochemistry, these techniques have allowed us to better understand tissue and organ biology in situ. Success with each of these methods is dependent on the adequate preparation of material. In this article, we describe the basic steps required to prepare tissue for routine histochemical analysis.Histochemical techniques routinely use frozen and paraffin-embedded tissue as a basis for cellular and morphological analysis. Freezing tissue results in less alteration to epitopes and therefore may offer improved staining characteristics compared t..
