EOSIN CAS 17372-87-1
ʻO eosin Y hiki ke hoʻoheheʻe ʻia i ka wai he mea hoʻoheheʻe ʻakika i hoʻokaʻawale ʻia i loko o nā anion i hoʻopaʻa ʻole ʻia i loko o ka wai a hoʻopaʻa ʻia me nā cations maikaʻi o nā pūʻulu amino protein e hoʻopaʻa i ka cytoplasm. ʻO ka cytoplasm, nā keʻena koko ʻulaʻula, nā ʻiʻo, ka ʻiʻo pili, nā granule eosin, a me nā mea ʻē aʻe i nā pae like ʻole o ka ʻulaʻula a i ʻole ka ʻulaʻula, e hana ana i kahi ʻokoʻa me ka nucleus polū.

ʻO Eosin kahi mea hoʻonani maikaʻi no ka cytoplasm. Hoʻohana maʻamau me nā mea pena ʻē aʻe e like me hematoxylin a i ʻole methylene blue. Hoʻohana ʻia ma ke ʻano he mea hoʻonaninani biological. Hoʻohana ʻia ʻo EOSIN ma ke ʻano he hōʻailona adsorption no ka hoʻoholo ʻana i ka titration precipitation o Br -, I -, SCN -, MoO, Ag +, etc.
Hoʻopili pinepine ʻia i ka 25kg / pahu, a hiki ke hana ʻia i ka pōʻai maʻamau.
