Fig 2. Alpha-toxin induced flip-flop motion in A549 cells.

Fig 2

A549 cells were treated with 1.0 μg/mL wild-type alpha-toxin (A) or H148G alpha-toxin (B) in the presence of Alexa Fluor 488-conjugated annexin V. Fluorescence and differential interference contrast images were acquired at 0, 10, 20, and 30 min after the addition of alpha-toxin. Scale bar, 10 μm.
