Applications

Eosin Yellowish noted to reduce the affinity of Mg2+-ATPase for ATP and increase the enzyme affinity for Mg2+ at concentrations of 10-50 ?M. At higher concentrations near 100 ?M 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 is also used to stain structures such as muscle, cytoplasm, and collagen. This agent also enhances fluorescent quenching abilities by forming a complex with polyvinulpyrrolidone.

Notes

Keep container tightly sealed. Store in cool, dry conditions in well sealed containers. Incompatible with oxidizing agents.
