Abstract
The process comprises subjecting the hemolyzed blood to a clarification step at a pH of between 4 and 6 in the presence of less than 15% of alcohol, then, after concentration, effecting a chromatography by exchange of anions so as to separate the hemoglobin, the albumin being thereafter eluted. The hemoglobin and the globulins may then be separated out by precipitation with 25% alcohol at a pH of 7. The proteins obtained are in the native state.
