Comparison between theoretical and experimental values. a Graph representing the theoretical relationship between the radius of vesicles and the osmotic pressure [21, 33]. Note that no formal solution exists for extremely hypotonic values (hashed region). b Comparison of the values of the allosteric constant determined experimentally (circle) or calculated theoretically (star) for different osmotic pressures. Data are plotted as where is the allosteric constant value in isotonic conditions. Note that theoretical and experimental data are highly concordant. Theoretical values are not provided for hypotonic conditions where the theory does not provide formal solutions (equivalent to the hashed region in (a))
