The present invention relates to a method for removing factor XI (FXI) when purifying plasma proteins and, more particularly, to a method for removing FXI with a cation exchange resin made of a ceramic material after concentration with dialysis of a plasma protein fraction II paste containing FXI and plasma proteins. As the method for removing FXI according the present invention increases the removal efficiency of impurities and thrombogenic materials, plasma proteins that are stable and have improved quality can be produced. |
