IMMUNOGLOBULIN PURIFICATION METHOD AND IMMUNOGLOBULIN PURIFICATION DEVICE, AND IMMUNOGLOBULIN PRODUCTION METHOD AND IMMUNOGLOBULIN PRODUCTION DEVICE

摘要

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.
