Iyini i-EOSIN CAS 17372-87-1?

I-eosin Y encibilikayo emanzini ingudayi one-asidi owenziwe ngamakhemikhali ohlukana ube ama-anion ashajwa kabi emanzini futhi abophe ama-cations afakwe kahle amaqembu amaprotheni ama-amino ukuze angcolise i-cytoplasm. I-cytoplasm, amangqamuzana egazi abomvu, imisipha, izicubu ezixhumeneyo, ama-eosin granules, njll. angcoliswe ngamazinga ahlukahlukene obomvu noma obomvana, enza umehluko obukhali nenucleus eluhlaza okwesibhakabhaka.

Isicelo

I-Eosin ingudayi omuhle we-cytoplasm. Ivamise ukusetshenziswa ngokuhlangana nabanye odayi njenge-hematoxylin noma i-methylene blue. Isetshenziswa njenge-ejenti ye-biological staining. I-EOSIN iphinda isetshenziswe njengenkomba ye-adsorption yokunqunywa kwe-titration yemvula ye-Br -, I -, SCN -, MoO, Ag+, njll. Isetshenziswa njenge-ejenti ye-chromogenic yokunqunywa kwe-fluorescence photometric ye-Ag+, Pb2+, Mn2+, Zn2+, njll.
