Confocal fluorescence microscopy of control (A and B) and C3-treated (C–F) NRK cells stained with antibodies to Man II (A, C, E, and G) and with TRITC-phalloidin (B, D, F, and H). The C3-induced disassembly of the actin stress fibers does not alter the reticular and perinuclear morphology of the Golgi complex.
