Tohu Hua

He aha te EOSIN CAS 17372-87-1?

Ko te eosin Y te wairewa te wai he waikano waikawa kua whakahiatotia matū e wehe ana ki nga anion toraro i roto i te wai ka herea ki nga cations pai o nga roopu amino pūmua hei poke i te cytoplasm. Ko te cytoplasm, ko nga toto toto whero, ko nga uaua, ko te kopa hono, ko nga granules eosin, me etahi atu ka poke ki nga nekehanga rereke o te whero, te mawhero ranei, ka puta he rerekee ki te karihi kikorangi.

Taupānga

He waikano pai te Eosin mo te cytoplasm. I te nuinga o te wa ka whakamahia tahi me etahi atu tae penei i te hematoxylin me te methylene blue. Ka whakamahia hei kai whakapouri koiora. Ka whakamahia ano te EOSIN hei tohu whakauru mo te whakatau i te rerenga rerenga o Br -, I -, SCN -, MoO, Ag+, me etahi atu Ka whakamahia hei kaihoko chromogenic mo te whakatau photometric fluorescence o Ag+, Pb2+, Mn2+, Zn2+, etc.
