Abstract
Process for the production of a highly purified S-sulfonated gammaglobulin by treating an S-sulfonated gammaglobulin obtained by sulfonating a conventional gammaglobulin with an ion exchanger in a buffer solution for development, and thereby absorbing single molecular S-sulfonated gammaglobulin thereto, and eluting the single molecular S-sulfonated gammaglobulin with a buffer solution for elution. This process can give the desired S-sulfonated gammaglobulin having a high content of single molecule and an extremely small anticomplementary activity (e.g. CH.sub.50 of 10% or less) and also an excellent shaking stability from the conventional gammaglobulin in an industrial scale.
