Chii chinonzi EOSIN CAS 17372-87-1?

Mvura inonyungudika eosin Y idhayi ine acidic yakagadzirwa nemakemikari inopatsanurwa kuita maanioni anochajiswa zvisina kunaka mumvura uye inosunga nema cations ane chaji yeprotein amino mapoka kuti asvibise cytoplasm. The cytoplasm, masero matsvuku eropa, tsandanyama, connective tissue, eosin granules, etc. zvakasvibiswa kune akasiyana madhigirii matsvuku kana epingi, achigadzira mutsauko wakajeka neblue nucleus.
