生化机理 | Eosin B is a xanthene dye and is also referred to as eosin bluish or erythrosin B. It is used in the Harris stain for Negri bodies. Eosin B is also used in Mayer’s Hemalum as a counterstain for collagen. Eosin B-Azure A are used together for the staining of cell granules, nuclei and microorganisms. It can also be used for protein estimation. The protein - eosin B complex absorbs at wavelength range of 536–544nm and the change in blue shift helps in determining the protein concentration. |
