Relative density of immunostained RBC treated with primary antibody against phosphorylated RBC-NOS Ser1177; RBC incubated with the phenazine methosulfate (PMS) and the addition of a superoxide scavenger (Tiron) are reported as relative changes compared with Control RBC. ∗∗∗∗p < 0.0001 significantly different compared with Control, ∗p < 0.05 significantly different compared with Control. Error bars absent for Control, due to relative measurement.
