CAS 17372-87-1: Eosin
Beschreibung:
Eosin, mit der CAS-Nummer 17372-87-1, ist ein synthetischer Farbstoff, der zur Klasse der Xanthene-Farbstoffe gehört. Er wird hauptsächlich als biologischer Farbstoff in der Histologie und Zytologie verwendet, um die Visualisierung von Zellstrukturen unter dem Mikroskop zu ermöglichen. Eosin zeichnet sich durch seine lebendige rot-rosa Farbe aus, die aus seinem konjugierten Doppelbindungssystem resultiert, das eine effektive Lichtabsorption ermöglicht. Der Farbstoff ist in Wasser und Alkohol löslich, was ihn vielseitig für verschiedene Anwendungen macht. Eosin wird häufig in Kombination mit Hämatoxylin in Färbeprotokollen verwendet, wo er einen Kontrast zu den blau gefärbten Zellkernen bietet und das Zytoplasma sowie andere Zellbestandteile hervorhebt. Darüber hinaus zeigt Eosin fluoreszierende Eigenschaften, die in der Fluoreszenzmikroskopie genutzt werden können. Es ist wichtig, Eosin mit Vorsicht zu behandeln, da es bei Kontakt mit Haut oder Augen Reizungen verursachen kann. Insgesamt ist Eosin ein wertvolles Werkzeug in der biologischen Forschung und Diagnostik, das bei der Untersuchung der Gewebemorphologie und der zellulären Eigenschaften hilft.

CAS:Eosin Y disodium salt is a water-soluble compound that is used as a fluorescent stain for biological samples. The compound has been shown to be toxic to mice, producing acute toxicities at high concentrations. Eosin Y also has a blue color and can be used to identify the presence of copper in vivo. Eosin Y is an effective agent for the treatment of wastewater, especially when combined with benzalkonium chloride. It can also be used in the treatment of skin cancer and has been shown to inhibit tumor growth in mice. The optimum concentration of eosin Y for staining is 1% in H2O.Formel:C20H6Br4Na2O5Reinheit:Min. 95%Molekulargewicht:691.85 g/molEosin Y, pure, Indicator grade

CAS:Formel:C20H6Br4Na2O5Farbe und Form:Brownish red, PowderMolekulargewicht:691.85Eosin 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.Formel:C20H6Br4Na2O5Reinheit:Min. 95%Farbe und Form:Brown PowderMolekulargewicht:691.85 g/molEosin Yellowish
