Charge distributions were obtained from BALB/c and B6D2F1 fibers. Values listed are mean (SEM) of best parameters in fits with Eq. 1. Free Ca²⁺ and Mg²⁺ concentrations are in mM. Data for 1.8 mM Ca²⁺ are the same as in Table 1; they are included here to facilitate comparison. Q_max in both strains did not differ significantly in any of the conditions tested.
