Abstract
The present invention relates to a preparation method of a human plasma-derived hepatitis B immunoglobulin preparation. More specifically, the present invention relates to a preparation method of a human plasma-derived hepatitis B immunoglobulin preparation characterized in that plasma protein fraction II (fraction II) containing human hepatitis B immunoglobulin is dialysis concentrated and then thrombus-producing materials and impurities formed during processes are removed by anion exchange resin and cation exchange resin purification techniques. By using the preparation method of the human plasma-derived hepatitis B immunoglobulin preparation according to the present invention, the efficiency of removing impurities and thrombus-producing materials is increased and a polymer content is maintained, whereby it is possible to produce human hepatitis B immunoglobulin with stable and improved quality.
