CAS 17372-87-1: Eosina
Descrição:
Eosina, com o número CAS 17372-87-1, é um corante sintético pertencente à classe dos corantes xantênicos. É utilizado principalmente como um corante biológico em histologia e citologia, permitindo a visualização de estruturas celulares sob um microscópio. Eosina é caracterizado por sua vibrante cor vermelha a rosa, que resulta de seu sistema de ligações duplas conjugadas que permite uma eficaz absorção de luz. O corante é solúvel em água e álcool, tornando-o versátil para várias aplicações. Eosina é frequentemente utilizado em combinação com hematoxilina em protocolos de coloração, onde fornece contraste aos núcleos corados de azul, destacando o citoplasma e outros componentes celulares. Além disso, Eosina exibe propriedades de fluorescência, que podem ser utilizadas em microscopia de fluorescência. É importante manusear Eosina com cuidado, pois pode causar irritação ao contato com a pele ou os olhos. No geral, Eosina é uma ferramenta valiosa na pesquisa biológica e no diagnóstico, auxiliando no estudo da morfologia dos tecidos e das características celulares.

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.Fórmula:C20H6Br4Na2O5Pureza:Min. 95%Peso molecular:691.85 g/molEosin Y, pure, Indicator grade

CAS:Fórmula:C20H6Br4Na2O5Cor e Forma:Brownish red, PowderPeso molecular: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.Fórmula:C20H6Br4Na2O5Pureza:Min. 95%Cor e Forma:Brown PowderPeso molecular:691.85 g/molEosin Yellowish
