Figure 5. Dependence of current densities on the concentration of ADPR, in the presence of either a high or a low [Ca2+].
Current densities (mean±S.E.M.) at low [Ca2+] (open circles) were significantly (Mann–Whitney U test) lower than that at high [Ca2+] (closed circles) for each ADPR concentration. The number of experiments is indicated for each experimental condition.
