亲和组织化学(Affinity Histochemistry)是利用一种物质对某一种组织成份的高度亲和能力发展起来的细胞、组织化学。亲和组织化学包括抗原与抗体、凝集素与糖类、生物素与抗生物素、葡萄球菌A蛋白与HgG、阳离子与阴离子、激素与受体、维生素、糖、以及类脂质等。亲和组织化学是免疫组织化学的进一步扩大和发展,比单纯的免疫组化方法 Affinity Histochemistry is the cellular and histochemical chemistry that develops from the high affinity of a substance to a certain tissue component. Affinity histochemistry includes antigens and antibodies, lectins and saccharides, biotin and avidin, staphylococcal protein A and HgG, cations and anions, hormones and receptors, vitamins, sugars, and lipidoids. Affinity histochemistry is the further expansion and development of immunohistochemistry, compared to a simple immunohistochemical method.
