Effect of photochemical treatment on intracellular localization of FITC-dextran. (A,B) Fluorescence micrographs. THX cells were incubated with 20 μg ml⁻¹ AlPcS_2a for 18 h followed by a 4 h incubation in AlPcS_2a-free medium. Then the cells were either kept in the darkness (A) or exposed to light for 4 min (B) before a 3 h incubation with 5 mg ml⁻¹ FITC-dextran.
