ʻEOSIN CAS 17372-87-1
ʻO ka eosin Y hiki ke hoʻoheheʻe ʻia i ka wai he dye acidic i hana ʻia me ke kemika e hoʻokaʻawale i nā anions i hoʻopiʻi maikaʻi ʻole ʻia i loko o ka wai a hoʻopaʻa me nā cation i hoʻopiʻi maikaʻi ʻia o nā hui amino protein e hoʻoluʻu i ka cytoplasm. ʻO ka cytoplasm, nā hunaola koko ʻulaʻula, nā ʻiʻo, nā ʻiʻo pili, nā granules eosin, a me nā mea ʻē aʻe ua hoʻoluʻu ʻia i nā kekelē like ʻole o ka ʻulaʻula a poni paha, e hana ana i kahi ʻokoʻa ʻoi me ka nucleus polū.

He mea hoʻoluʻu maikaʻi ʻo Eosin no ka cytoplasm. Hoʻohana pinepine ʻia me nā mea hoʻoluʻu ʻē aʻe e like me ka hematoxylin a i ʻole ka methylene blue. Hoʻohana ʻia ma ke ʻano he mea hoʻoluʻu olaola. Hoʻohana ʻia ʻo EOSIN ma ke ʻano he hōʻailona adsorption no ka hoʻoholo ʻana i ka titration precipitation o Br -, I -, SCN -, MoO, Ag+, a pēlā aku. Hoʻohana ʻia ma ke ʻano he mea chromogenic no ka hoʻoholo photometric fluorescence o Ag+, Pb2+, Mn2+, Zn2+, a pēlā aku.
Hoʻopili pinepine ʻia i loko o 25kg / pahu, a hiki ke hana ʻia kahi pūʻolo i hoʻopilikino ʻia.
