Eosin is most often used as a counterstain to haematoxylin in H&E (haematoxylin and eosin) staining. H&E staining is one of the most commonly used techniques in histology. | [Definition]
ChEBI: An organic sodium salt that is 2',4',5',7'-tetrabromofluorescein in which the carboxy group and the phenolic hydroxy group have been deprotonated and the resulting charge is neutralised by two sodium ions. | [Preparation]
countries called red. Fluorescent element (C.I. Acid Yellow 73, C.I. 45350) in water or ethanol solution bromine into four bromine derivatives, and then into sodium salt. | [Flammability and Explosibility]
Notclassified | [Biological Activity]
ami5/eosin y disodium salt is a non-selective protein methyltransferase inhibitor.post-translational protein methylation at lysine and arginine residues is related to the gene expression regulation. the enzymatic activities of protein methyltransferases serve to do covalent modifications in the control of gene transcription. | [in vitro]
ami5/eosin y disodium salt has been identified as a competitive inhibitor of sam binding and had been shown to inhibit not only prmts but also lysine methylation by the set7 and disruptor of telomeric silencing 1-like (dot1l) mtases in vitro. both ami5/eosin y disodium salt and its analog ami-1 have been used as lead compounds for the development of novel mtase-specific inhibitors. moreover, it was found that ami5/eosin y disodium salt could inhibit set7 in vitro and decrease h3k4m1 in vascular endothelial cells.

yellow peach. Orange powder, soluble in water and ethanol with fluorescent blue light is yellowish red solution. Meet strong sulfuric acid yellow, it will be diluted yellow light red precipitate generated. Dyeing copper ions in the blue colour and lustre; Iron ion colour and lustre in the dark blue. Discharge the gender is good. Mainly used in red ink and red pencils, only comfortable carpet dyeing. After refining can be used as medicine and cosmetics of coloring. Can also be used in leather dyeing. The aluminum salt can be used as organic pigments.

Dissolve it in the minimum volume of H2O (1g/mL), filter and add EtOH until separation of salt is complete. Filter the solid off, wash it with absolute EtOH, then Et2O and dry it first in air, then at 100o. It is used for staining blood cells and for estimating traces of Ag.
