TABLE 2.

Rate constant of SO₄ ²⁻ uptake, time needed to reach equilibrium, and SO₄ ²⁻ quantity internalized by either RBCs untreated or treated as indicated. Data are presented as means ± S.E.M. from (n) separate experiments. ns not statistically significant versus untreated (control); ***p < 0.001 versus untreated; ° p < 0.01 versus 100 mM D-Gal, as attested by one-way ANOVA followed by Bonferroni’s multiple comparison post hoc test.
