He aha te EOSIN CAS 17372-87-1?

Ko te eosin Y wairewa i te wai he tae waikawa i hangaia e te matū e wehewehe ana hei anion utu kino i roto i te wai, ā, ka herea ki ngā kationa utu pai o ngā rōpū amino pūmua hei whakapoke i te cytoplasm. Ko te cytoplasm, ngā toto whero, ngā uaua, ngā kiko honohono, ngā granules eosin, me ētahi atu, ka pania ki ngā taumata whero, māwhero rānei, ka hanga he rerekētanga koi ki te karihi kikorangi.

Tono

He tae pai te Eosin mō te cytoplasm. He tikanga tēnei hei whakamahi tahi me ētahi atu tae pērā i te hematoxylin, te methylene blue rānei. Hei mea whakakoi koiora. Ka whakamahia hoki te EOSIN hei tohu mimiti mō te whakatau i te titration o te Br-, I-, SCN-, MoO-, Ag+, me ētahi atu. Hei mea whakakōromāota mō te whakatau i te fluorescence photometric o Ag+, Pb2+, Mn2+, Zn2+, me ētahi atu.
