在肿瘤病理组织切片的常规“ＨＥ”染色中，国内外多使用哈瑞（Ｈａｒｒｉｓ）苏木素试剂为染液，但配制过程比较复杂，配方中的氧化剂为氧化汞，易造成环境污染，影响人体健康。苏木素用量过大易产生大量的氧化物漂浮于表面，玷污切片，不易洗净。近年来国内外学者对其配方进 In the routine “HE” staining of tumor pathological tissue sections, Harris hematoxylin reagent is used as the dyeing liquid at home and abroad, but the preparation process is complicated. The oxidizing agent in the formulation is mercury oxide, which can easily cause environmental pollution and affect human health . Excessive amount of hematoxylin easy to produce a lot of oxide floating on the surface, stained slices, not easy to wash. In recent years, scholars at home and abroad to its formula
