Figure 6. Effect of 8-bromo-cAMP and adrenaline on CMF amplitudes in normal and ATP-depleted RBCs.

Normal (□) and ATP-depleted (
) RBCs were incubated for 20 min with 10−4 M 8-bromo-cAMP and 10−7 M adrenaline, at 37 °C. The amplitudes are given by δImax/I (%; means ±s.e.m.), where n (given in parentheses) is the number of RBCs tested.
