Fig. 2. Knockdown of mLgl suppresses disassembly of apical proteins during the depolarization of MDCK cells. Confluent monolayers were incubated with mouse anti-gp135 antibody for 1 hour. After washing out the antibody, the cells were incubated with LC medium for the indicated time. The cells were fixed, permeabilized and stained with Alexa Fluor 488-conjugated anti-mouse IgG together with Rhodamine-phalloidin. (A) Projected views of optical sections from the apical to the basal membranes of cells. (B) Confocal z-sections. Arrowheads indicate cells with intracellular gp135 and F-actin staining. Bars, 20 µm.
