伊红y染料是常规病理组织切片染色中胞浆较理想的染色剂。组织切片染色的优良，对肿瘤的诊断有着重要的意义。伊红染料虽常规配方较多，但在操作及染色效果等方面不够理想，为此，我们对伊红y染色液配制进行了改进。改进后的方法具有操作简便、经济、染色性质稳定、着色力强且 Eosin y dye is an ideal cytoplasm stain in routine pathological tissue staining. The excellent staining of tissue sections has important implications for the diagnosis of tumors. Erythromycin dyes have more conventional formulas, but they are not ideal in terms of handling and dyeing effects. For this reason, we have improved the preparation of eosin y dyeing solutions. The improved method has the advantages of easy operation, economy, stable dyeing properties and strong coloring power.
