Effect of streptomycin on deoxygenation-induced PS exposure in RBCs from SCD patients. PS exposure is normalised to exposure in RBCs at time 0, just before addition of streptomycin, which was 5.7 ± 0.8 % (indicated by the dotted line), and after 30 and 60 min deoxygenation in the absence (solid black histograms) or presence (lighter histograms) of streptomycin at 10, 50 and 100 μM. Data represent means ± S.E.M., n = 9. All N.S. compared to deoxygenated RBCs in the absence of streptomycin
