Effect of PKC inhibitors on ChTX-sensitive K⁺ influx in normal erythrocytes.

Cells were preincubated with the different inhibitors of PKC, and K⁺ influx was determinate as a function of ionized extracellular Ca⁺⁺ in the presence of A23187 as described in “Materials and methods.” Staurosporin, 5 μM; calphostin C, 1 μM; chelerythrine, 10 μM. Values are means of triplicate determinations.
