(a) Plots of log (〈x2〉/t) versus logt for Ca2+ in the presence of either stationary or mobile buffer at [Bi]0 = 2.64 μM and 26.4 μM; (b) time evolutions of Ca2+ and Ca2+-bound buffers (CaB) concentrations, where [Bm]0 = 26.4 μM, and the total calcium concentration (CaT) is also shown; (c) plots of the instantaneous anomalous diffusion exponent (αins) versus logt, for different values of [Bm] and [Bs]. |
