Indirect immunofluorescence of occludin in the MDCK. (A) Control cells; (B) cells exposed to H2O2 (100 µM, for 2 hr); (C) cells exposed to zymosan (200 µl of stock solution 1 mg/ml, for 4 hr); (D) H2O2-exposed cells incubated with 3-AB (3 mM); (E) H2O2-exposed cells incubated with NAC (10 mM); (F) represent the transmission light of control cells. MDCK, Madin-Darby Canine Kidney cells; 3-AB, 3-aminobenzamide; NAC, n-acetylcysteine.
