Title:
免疫グロブリン精製方法及び免疫グロブリン精製装置、並びに免疫グロブリン製造方法及び免疫グロブリン製造装置
Document Type and Number:
Japanese Patent JP7090300
Kind Code:
B2
Abstract:
To provide an immunoglobulin purification method which achieves a high immunoglobulin recovery percentage without causing loss of the antibody nature of an immunoglobulin. The immunoglobulin purification method includes an adsorption step and a desorption step. The adsorption step involves adsorption of an immunoglobulin onto porous zirconia particles in a neutral buffer. The desorption step involves desorption of the immunoglobulin adsorbed on the porous zirconia particles from the porous zirconia particles by means of a neutral desorption liquid.
