PROCESS FOR PREPARING THE PRINCIPAL PROTEINS OF HAEMOLYZED BLOOD IN THE NON-DENATURED FORM ABSTRACT The process comprises subjecting the haemolyzed 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 haemoglobin, the albumin being thereafter eluted. The haemoglobin 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.
