EOSIN CAS 17372-87-1 yog dab tsi?

Dej soluble eosin Y yog cov tshuaj sib xyaw ua ke acidic dye uas dissociates rau hauv qhov tsis zoo them nyiaj anions hauv dej thiab khi nrog cov txiaj ntsig zoo ntawm cov protein amino pawg kom stain lub cytoplasm. Cov cytoplasm, cov qe ntshav liab, cov leeg, cov ntaub so ntswg, cov eosin granules, thiab lwm yam yog stained rau txawv degrees ntawm liab los yog liab dawb, ua ib tug ntse sib piv nrog cov xiav nucleus.
