Fig. 6. Characterization of F-dexabinding to the cell membrane of AtT-20 cells. Examples of intensity fluctuations (normalized scale, measurement time: 30 seconds) and measured and calculated corresponding autocorrelation curves G(
) at the cell-membrane-position for F-dexa after preincubation with (A) binding buffer as a control, and after preincubation with (B) RU486 or (C) PTX.
