ABSTRACT:
A method for producing gamma-globulin in its native state derived from human sources and suitable for use in intravenous administration and having an anti-complementary activity of lower than 20% (C'H.sub.50 v) is disclosed, in which raw human gamma globulin is brought into suspension in an aqueous solution of a monosaccharide, disaccharide or sugar alcohol, adjusted to a pH value of 7.0 to 9.0 and then subjected to fractional precipitation by adding dextran thereto. The fractions showing anti-complementary activity are removed as precipitates.
