Hemoglobin oxidation at functional amino acid residues during routine storage of red blood cells

BACKGROUND Routine storage of red blood cells (RBCs) results in the progressive accumulation of storage lesions. While the clinical relevance of these lesions is still a matter of debate, alterations to RBC morphology and biochemistry, especially in terms of energy and redox homeostasis, are likely to affect RBC physiology and functionality at a minimum. Identification of oxidative modifications that accumulate on key RBC proteins will help...
