FRAP measurements on a 12% w/w pH 3.5 BLG gel, depicted in two columns for FD70 and NaFL respectively. All depicted measurements are performed with 100 ppm probe concentration. (Top) Recovery curves; the fits to the recovery curves are gained in the no-binding limit with D = 6.7 μm2/s and R2 = 0.9996; and D = 24.0 μm2/s and R2 = 0.9941, for FD70 and NaFL, respectively. (Bottom) Diffusion coefficients, obtained using the MLH script, as a function of the number of analyzed postbleach images (two frames per second).
