Panoramica

È stato osservato che l'eosina Y, un colorante rosso xantene, riduce l'affinità della Mg2+-ATPasi per l'ATP e aumenta l'affinità dell'enzima per il Mg2+ a concentrazioni di 10-50 μM. A concentrazioni più elevate, vicine ai 100 μM, è stata dimostrata una riduzione dell'affinità della Mg2+-ATPasi per l'attivatore ionico. Questo composto è stato anche segnalato come fotosensibilizzatore che funziona come fotoelettrodo molecolare attraverso la catalizzazione della reazione di trasferimento di elettroni guidata dalla luce visibile. L'eosina Y è stata utilizzata per colorare strutture come il muscolo, il citoplasma e il collagene. Questo agente migliora anche le capacità di spegnimento della fluorescenza formando un complesso con il polivinulpirrolidone.

Nota
Per quanto possibile, si consiglia di preparare e utilizzare le soluzioni lo stesso giorno. Tuttavia, se è necessario preparare in anticipo le soluzioni di riserva, si consiglia di conservarle in aliquote in fiale ben chiuse a -20°C. In genere, queste possono essere utilizzate per un mese. In genere, queste soluzioni sono utilizzabili fino a un mese. Prima dell'uso e dell'apertura della fiala, si consiglia di lasciare che il prodotto si equilibri a temperatura ambiente per almeno 1 ora. Per ulteriori informazioni, consultare la SDS.
