摘要

of the disclosure The protein PP18 which has the following characteristics: a) an electrophoretic mobility in the region of that of .beta.1-globulins; b) an isoelectric point between 5.6 and 6.2; c) a sedimentation coefficient s20,w of 5.0 ? 0.2 s; d) a molecular weight determined in an ultracentrifuge of 82,300 ? 5,600; e) a carbohydrate fraction of 2.3 + 1.3 g/100 g.(mannose 0.15 ? 0.1, xylose (?) 0.5 + 0.5, galactose 0.5 ? 0.2, glucose 0.2 ? 0.1, N acetylglucosamine 0.7 ? 0.2, and N-acetylneuraminic acid 0.25 + 0.2, each g/100 g). and a specified amino acid composition, and a process for obtaining it and its use, are described.
