Figure 8. Effects of extracellular Ca2+
and Mg2+ on YO-PRO-1 uptake. Both Ca2+ and Mg2+
decreased YO-PRO-1 uptake but Ca2+ has a more potent effect
than Mg2+. Ca2+ and Mg2+ together have a synergic
effect on the decrease in YO-PRO-1 uptake. The double asterisk
indicates a p<0.01 compared to PBS and the triple asterisk denotes a
p<0.001 compared to PBS.
