The present invention relates to a method for purifying immunoglobulin, more specifically to a method for purifying immunoglobulin characterized by concentrating plasma protein fraction II paste containing immunoglobulin via dialysis, then discarding the products of thrombosis by means of a ceramic cation exchange resin purification technique, and maintaining a low polymer content by maintaining a set saline concentration during elution. When the method for purifying immunoglobulin according to the present invention is used, impurities and products of thrombosis are removed with greater efficiency, and the polymer content can be maintained, thereby allowing immunoglobulin having a stable and enhanced quality to be produced. |
