Kodi EOSIN CAS 17372-87-1 ndi chiyani?

Eosin Y yosungunuka m'madzi ndi utoto wa acidic wopangidwa ndi mankhwala womwe umagawanika kukhala ma anion omwe ali ndi mphamvu yoipa m'madzi ndipo umalumikizana ndi ma cation a protein amino groups omwe ali ndi mphamvu yoipa kuti adetse cytoplasm. Cytoplasm, maselo ofiira a magazi, minofu, minofu yolumikizana, ma granules a eosin, ndi zina zotero zimadetsedwa mpaka madigiri osiyanasiyana ofiira kapena pinki, zomwe zimapangitsa kuti pakhale kusiyana kwakukulu ndi nucleus yabuluu.

Kugwiritsa ntchito

Eosin ndi utoto wabwino wa cytoplasm. Nthawi zambiri umagwiritsidwa ntchito limodzi ndi utoto wina monga hematoxylin kapena methylene blue. Umagwiritsidwa ntchito ngati choyezera utoto chachilengedwe. EOSIN imagwiritsidwanso ntchito ngati chizindikiro cha adsorption poyesa Br -, I -, SCN -, MoO, Ag+, ndi zina zotero. Umagwiritsidwa ntchito ngati choyezera chromogenic poyesa kuwala kwa Ag+, Pb2+, Mn2+, Zn2+, ndi zina zotero.
