:Éosine
Description :
Éosine, avec le numéro CAS 17372-87-1, est un colorant synthétique appartenant à la classe des colorants xanthéniques. Il est principalement utilisé comme colorant biologique en histologie et cytologie, permettant la visualisation des structures cellulaires au microscope. Éosine se caractérise par sa couleur rouge à rose vibrante, qui résulte de son système de doubles liaisons conjuguées permettant une absorption efficace de la lumière. Le colorant est soluble dans l'eau et l'alcool, ce qui le rend polyvalent pour diverses applications. Éosine est souvent utilisé en combinaison avec l'hématoxyline dans les protocoles de coloration, où il fournit un contraste avec les noyaux colorés en bleu, mettant en évidence le cytoplasme et d'autres composants cellulaires. De plus, Éosine présente des propriétés de fluorescence, qui peuvent être utilisées en microscopie de fluorescence. Il est important de manipuler Éosine avec précaution, car il peut provoquer des irritations au contact de la peau ou des yeux. Dans l'ensemble, Éosine est un outil précieux dans la recherche biologique et le diagnostic, aidant à l'étude de la morphologie des tissus et des caractéristiques cellulaires.

100mg114,00€Eosin Y disodium salt
CAS :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.Formule :C20H6Br4Na2O5Degré de pureté :Min. 95%Couleur et forme :Brown PowderMasse moléculaire :691.85 g/molRef: 3D-FE01492
