Mean squared displacement of ER tubule oscillations in live Vero cells. (a) Fluorescence image of a single ER tubule. The tubule position along the purple line was tracked. (b) Fluorescent intensity along the line in (a), with krig interpolation and the centre of the fit depicted. (c) MSDs of measured transverse tubule fluctuations as a function of lag time. Traces begin at different time points due to slight differences in video frame rates. (d) Exponents of the power law fit to the MSDs in (c). Dotted line shows lognormal fit with mean exponent 0.54 ± 0.04.
