Fig. 4. Lateral diffusion of FITC-LPS bound to cells. FRAP curve of FITC-LPS bound to CHO-CD14 cells (A,B) and measured at 22°C (A) or at 37°C (B). FRAP curve of FITC-LPS bound to MonoMac 6 cells (C,D) and measured at 22°C (C), or at 37°C (D). FRAP curve of FITC-LPS bound to ECV-304 (E,F) cells and measured 22°C (E), or at 37°C (F). The best fit to the experimental data is shown. The diffusion coefficient of FITC-LPS bound to cells was the mean and standard deviation from several (10) individual curves.
