Methemoglobin reduction in red cells: effect of a high oxygen affinity hemoglobin.
Erythrocytes from heterozygous carriers of the high oxygen affinity mutant hemoglobin, Hb Wood, demonstrate lower rates of methemoglobin reduction than normal human red cells when incubated in the in vitro system of Beutler and Baluda. The rate of methemoglobin reduction in red cells from an individual who is heterozygous for both NADH-methoglobin reductase deficiency and Hb Wood shows the combined effects of the two mutations.
