ABSTRACT:
The invention relates to new protein derivatives of blood, blood-protein containing raw materials and hemoglobin, and more particularly to processed globin products, and to processes for producing these products. The processed globin products have an isoelectric point at a pH value below 5.5, an iron content of less than 1000 ppm, a ratio of His : Lys between 0.6 and 1.5, a Tyrosine content of at least 0.5% by weight, a Methionine content of at least 0.5% by weight, and a Lysine content of at least 5% by weight. The method for the production of the processed globin products according to the invention comprises treating the starting material at a pH above 12 and an the oxidizing treatment step the pH is kept below 12 while maintaining the temperature below 50.degree. C.
