General description
Eosin has been used in combination with methylene blue, to detect carboxlic acid group in organic compounds. It gives a red or orange-coloured precipitate on treatment with carboxylic acid solution in water, acetone, alcohol, or dioxin. It is also used as an indicator for differentiation of the colon from the typhoid-dysentery group of bacteria.
伊红和亚甲蓝染色的混合物，用于鉴别微生物培养基中培养和鉴定病原微生物，例如 干燥奈瑟球菌 、、 醋酸钙不动杆菌 。
Application
Eosin methylene blue was used for staining cells, during optical microscopy studies, done for analysis of cell morphology.
