1.Eosin Y, a red xanthene dye, has been noted to reduce the affinity of Mg2+-ATPase for ATP and increase the enzyme affinity for Mg2+ at concentrations of 10-50 μM. At higher concentrations near 100 μM the affinity for Mg2+-ATPase for the ion-activator has been shown to be reduced. This compound has also been reported to be a photosensitizer that works as a molecular photoelectrode via catalyzation of the visible-light-driven electron-transfer reaction. Eosin Y has been used to stain structures such as muscle, cytoplasm, and collagen. This agent also enhances fluorescent quenching abilities by forming a complex with polyvinulpyrrolidone.

2.Eosin Y is an acid dye that dyes cytoplasm into pink (eosinophilic). It is one of the commonly used staining reagents for tissue and cytochemistry. It is often combined with hematoxylin (a basic dye that dyes nuclei into purple-blue (alkaline). ())) Combined use (HE staining). In immunohistochemistry experiments, it is often used as a lining reagent to facilitate the observation of tissue and cell structure.

1. Used as an adsorption indicator, etc.

2. Biochemical research

3. Used as a biological stain. Also used as an adsorption indicator for precipitation titration determination of Br-, I-, SCN-, MoO, Ag+, and the like. Used as a color developer for the determination of Ag+, Pb2+, Mn2+, Zn2+, etc. by fluorescence spectrophotometry.

4. Biological staining agents, peptides and proteins, protoplasts, alkaline phosphatase, etc.; photometric determination of silver (sub-micrograms); Wright stain component (Wright stain) for the detection of blood cells; adsorption indicators, Titration of bromine, iodine, fluorine, etc.
