Wright stain - Introduction
This reagent is a compound neutral stain, composed of eosin and a compound composed of oxidized methylene blue that removes part of the methyl group. It has the effects of neutrophilic, basophilic and eosinophilic parts for the staining of protoplasts. Specially used for blood staining. The maximum absorption wavelength is 640(522)nm.

Wright stain - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| the application of | of the pigment, direct use, without any preparation process, dye solution plus a trace of neutral glycerol, to prevent methanol volatilization or oxidation, but also can make the blood cell staining more clear. Often used in blood and cell smears, bone marrow cell smears, bacterial staining. The cytoplasm was red, the nucleus and bacteria were blue, and the eosinophilic granules were orange. Reiter stain, direct use, without any preparation process, dye solution plus a trace of neutral glycerol, to prevent methanol volatilization or oxidation, but also can make blood cell staining more clear. Often used in blood and cell smears, bone marrow cell smears, bacterial staining. The cytoplasm was red, the nucleus and bacteria were blue, and the eosinophilic granules were orange. |
| effect | the staining of Reiter stain on cells has both physical adsorption and chemical affinity, the chemical properties of various cell components are different, and the affinity for various dyes is also different. Therefore, after dyeing with the dye liquid, on the same blood slice, you can see a variety of different colors, such as hemoglobin, eosinophilic particles for basic protein, and acid dye eosin results, dyed pink, called eosinophilic material; Nuclear protein and lymphocyte cytoplasm is acidic, combined with the basic dye methylene blue or azure, stained purple blue, called basophilic material; neutral particles are isoelectric state and eosin and methylene blue can be combined, dyed light purple, called neutral substances. |
| application range | stain for microscopic smear, such as blood, bone marrow staining, blood parasite staining (protozoa, leishmania, bloodshot, etc.). Biological staining. Microscopic smears with stains, such as blood, bone marrow staining, blood parasite staining (protozoa, Leishmania, bloodshot, etc.). |
| Use | used as biological stain A commonly used blood stain and its application in microbial staining |
| autoignition temperature | 393°C |
