  1. aHEPES, NaCl, and sucrose were supplemented to help keep the pH, final ionic strength and final osmolarity constant at 7.4, 170 mM, and 325–340 RT (where R is the gas constant and T is ambient temperature, and ideal solutions are assumed), respectively. Same buffers were used for all experiments through this work unless specified otherwise.
