Fig 3.
(a) Time evolution of the density of KDELR cargo signals at the surface of human cell lines after treatment with eGFP-RTAE177D-HDEL. The optimal signal-to-noise ratio, scaled by the cell periphery size, is shown as a function of time. The dashed lines show the fluctuation range of the signal intensity at the steady state. (b) Similar to panel (a) but for mouse cell lines. (c) Duration of transient and growth regimes and the mean relative saturation level of signal density (compared to the largest analyzed cells) in the steady state versus the cell size.
