HE染色是最基本的病理组织学染色,染细胞核的苏木素是HE染色过程中的关键,苏木素染色的好坏决定着细胞核的着色深浅,也决定了一张切片的质量[1]。苏木素染液的配制方法有很多,目前最常用的为Harris苏木素与Gill苏木素,这两种染液的染色原理虽然相同,但在实际配制与 Hematoxylin-eosin staining is the most basic histopathological staining. The hematoxylin which is the nucleus of the nucleus is the key to HE staining. The hematoxylin staining determines the color depth of the nucleus and determines the quality of a slice [1]. Hematoxylin dye preparation methods are many, the most commonly used for the Harris hematoxylin and Gill hematoxylin, the dyeing of the two dye although the same principle, but in the actual preparation and
