Role of Calcium in Phosphatidylserine Externalisation in Red Blood Cells from Sickle Cell Patients

Figure 3

Effect of extracellular K+ on phosphatidylserine (PS) exposure in red blood cells (RBCs) from sickle cell patients. RBCs were incubated for 18 hours with extracellular [ C a 2 + ] of 5 mM under oxygenated (20% O2) or deoxygenated (1% O2) conditions in either low K+-containing (extracellular [K+] of 5 mM) saline or high K+-containing (90 mM [K+]) saline. Histograms represent m e a n s ± S . E . M . ( 𝑛 = 3 ). 𝑃 < . 0 0 1 compare to LK oxy; # N.S. cf. LK oxy.
