Résumé : With this technique, the hemoglobin and enzymes of a human red cell hemolysate migrate through a pH gradient of 4 to 9, obtained with carrier ampholytes, within a thin layer of polyacrylamide gel. The red cell NAD(P)H : oxidoreductases are fractionated into three components, while the bulk of hemoglobin is resolved into four or five discrete bands. The procedure is particularly promising for the study of the NADH: methemoglobin oxidoreductase or its molecular variants and allows the use of crude red cell hemolysates. © 1971.
