CAS 17372-87-1
:Eosina
Descripción:
Eosina, con el número CAS 17372-87-1, es un colorante sintético que pertenece a la clase de los colorantes xanténicos. Se utiliza principalmente como un tinte biológico en histología y citología, permitiendo la visualización de estructuras celulares bajo un microscopio. Eosina se caracteriza por su vibrante color rojo a rosa, que resulta de su sistema de enlaces dobles conjugados que permite una efectiva absorción de luz. El colorante es soluble en agua y alcohol, lo que lo hace versátil para diversas aplicaciones. Eosina se utiliza a menudo en combinación con hematoxilina en protocolos de tinción, donde proporciona contraste a los núcleos teñidos de azul, destacando el citoplasma y otros componentes celulares. Además, Eosina exhibe propiedades de fluorescencia, que pueden ser utilizadas en microscopía de fluorescencia. Es importante manejar Eosina con cuidado, ya que puede causar irritación al contacto con la piel o los ojos. En general, Eosina es una herramienta valiosa en la investigación biológica y el diagnóstico, ayudando en el estudio de la morfología de los tejidos y las características celulares.

CAS:<p>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.</p>Fórmula:C20H6Br4Na2O5Pureza:Min. 95%Forma y color:Brown PowderPeso molecular:691.85 g/molEosin Yellow (water soluble) for cell culture, Endotoxin (BET) 1EU/mg
