Abstract

A method of the production of immunoglobulin having a high content of monr from immunoglobulin-containing materials by a fractionation method, which comprises carrying out the fractionation in the presence of a water-soluble, basic nitrogen-containing organic compound having a dissociation constant (pKb) of 7 or less or an acid addition salt thereof, and thereby inhibiting by-production of undesirable aggregated molecules. The immunoglobulin has a high content of monomer and contains no or little aggregated molecules and hence can be used as a medicine in immune prophylaxis and immunotherapy without undesirable side effects and can be administered by intraveneous route, and further, is useful for the preparation of chemically treated immunoglobulin having a high content of monomer.
