Chemical Property/Description:

 

This reagent is a composite neutral dye consisting of eosin and an oxidized methylene blue with partial removal of methyl groups. It has the function of neutral, basophilic and acidophilic parts in the staining of protoplasm. It is especially used in the dyeing of blood. Soluble in ethanol, insoluble in water. Maximum absorption wavelength 640(522)nm.
 

Main Uses:

 

Biological staining. Microscope smears with staining agents, such as blood, bone marrow staining, blood parasite staining (protozoa, Leishmania, bloodworm, etc.).

Wright's stain is a compound dye composed of acid dye Eosin and basic dye Methylene Blue, which has a good distinguishing effect on the dyeing of protoplasm. Giemsa staining solution is made of Azurin II non-eosin mixture, the staining principle and result are basically the same as that of Reye's staining method. Giemsa staining solution has strong staining power on cytoplasm and can better display the basophilic degree of cytoplasm, especially for azurin, eosinophilic and basophilic particles in blood and bone marrow cells, the staining is clear, but the staining of nuclei is darker and the nuclear structure is poor.
