Notes: Velaresol is an oxyhemoglobin (Hb-O2) stabilizer.{66160} It increases erythrocyte deformability in isolated human blood from a patient with sickle cell disease when used at a concentration of 1.5 mM. Velaresol (3 or 5 mM) inhibits deoxygenation-induced decreases in erythrocyte deformability in isolated human blood from a patient with sickle cell disease. It decreases oxygen tension and increases oxygen saturation of isolated human sickle erythrocytes when used at a concentration of 5 mM.{66159}
