Analyis of met-form haemoglobins in human erythrocytes of normal adults and of a patient with hereditary methaemoglobinaemia due to deficiency of NADH-cytochrome <i>b</i>5 reductase

Abstract

Isoelectric-focusing analysis on an Ampholine/polyacrylamide-gel plate revealed that met-form haemoglobins are present as half-oxidized haemoglobins such as the (alpha 2+ beta 3+)2 and (alpha 3+ beta2+)2 forms rather than as methaemoglobin in the erythrocytes of normal human adults and also of a patient with hereditary methaemoglobinaemia due to deficiency of NADH-cytochrome b5 reductase.
