CAS 17372-87-1: Eosina
Descrizione:
Eosina, con il numero CAS 17372-87-1, è un colorante sintetico appartenente alla classe dei coloranti xanteni. È utilizzato principalmente come colorante biologico in istologia e citologia, consentendo la visualizzazione delle strutture cellulari al microscopio. Eosina è caratterizzato dal suo vibrante colore rosso-rosa, che deriva dal suo sistema di doppi legami coniugati che consente una efficace assorbimento della luce. Il colorante è solubile in acqua e alcol, rendendolo versatile per varie applicazioni. Eosina è spesso utilizzato in combinazione con ematossilina nei protocolli di colorazione, dove fornisce contrasto ai nuclei colorati di blu, evidenziando il citoplasma e altri componenti cellulari. Inoltre, Eosina presenta proprietà di fluorescenza, che possono essere utilizzate nella microscopia a fluorescenza. È importante maneggiare Eosina con cura, poiché può causare irritazione al contatto con la pelle o gli occhi. In generale, Eosina è uno strumento prezioso nella ricerca biologica e nella diagnostica, aiutando nello studio della morfologia dei tessuti e delle caratteristiche cellulari.

CAS:Formula:C20H6Br4Na2O5Colore e forma:Brownish red, PowderPeso molecolare: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.Formula:C20H6Br4Na2O5Purezza:Min. 95%Colore e forma:Brown PowderPeso molecolare:691.85 g/molEosin Yellowish
