Iyini i-EOSIN CAS 17372-87-1?

I-eosin Y encibilikayo emanzini iyidayi ye-asidi eyenziwe ngamakhemikhali ehlukana ibe ama-anion ashajeke kabi emanzini futhi ihlangane nama-cation ashajeke kahle amaqembu ama-amino amaprotheni ukuze ifake i-cytoplasm. I-cytoplasm, amaseli egazi abomvu, imisipha, izicubu ezixhumeneyo, ama-granule e-eosin, njll. anombala ohlukahlukene obomvu noma opinki, okwenza umehluko omkhulu ne-nucleus eluhlaza okwesibhakabhaka.

Isicelo

I-Eosin iyidayi elihle le-cytoplasm. Ivame ukusetshenziswa kanye nezinye izidayi ezifana ne-hematoxylin noma i-methylene blue. Isetshenziswa njenge-ejenti yokupenda yezinto eziphilayo. I-EOSIN isetshenziswa futhi njengesibonakaliso sokufakwa kwe-adsorption ekunqumeni i-precipitation titration ye-Br -, I -, SCN -, MoO, Ag+, njll. Isetshenziswa njenge-chromogenic agent ekunqumeni i-fluorescence photometric ye-Ag+, Pb2+, Mn2+, Zn2+, njll.
