Yintoni i-EOSIN CAS 17372-87-1?

I-eosin Y enyibilikayo emanzini yidayi ye-asidi eyenziwe ngeekhemikhali eyahlukana ibe zii-anions ezitshajwe kakubi emanzini kwaye ibopha ngee-cations ezitshajwe kakuhle zamaqela ee-amino zeproteni ukuze ifake i-cytoplasm. I-cytoplasm, iiseli zegazi ezibomvu, izihlunu, izicubu ezidityanisiweyo, ii-granules ze-eosin, njl.njl. zidaywe ukuya kumanqanaba ahlukeneyo abomvu okanye apinki, zenza umahluko omkhulu kwi-nucleus eluhlaza okwesibhakabhaka.

Isicelo

I-Eosin yidayi elungileyo ye-cytoplasm. Idla ngokusetyenziswa kunye nezinye iidayi ezifana ne-hematoxylin okanye i-methylene blue. Isetyenziswa njenge-arhente yokudaya yebhayoloji. I-EOSIN ikwasetyenziswa njengesalathisi sokufunxa ukuze kumiselwe i-precipitation titration ye-Br -, I -, SCN -, MoO, Ag+, njl. Isetyenziswa njenge-chromogenic agent ukuze kumiselwe i-fluorescence photometric ye-Ag+, Pb2+, Mn2+, Zn2+, njl.
