    摘要: Herein is reported a method for selecting an antibody with a systematic clearance in cynomolgus monkeys of less than 8 mL/kg/day comprising the steps of measuring the retention time of the antibody on performing an FcRn affinity chromatography with a positive linear pH gradient and on a heparin affinity chromatography with a positive linear conductivity/salt gradient, and selecting an antibody that has a relative retention time on the FcRn affinity chromatography column is less than 1.78 times the retention time difference between peaks 2 and 3 the retention time of preparation of an oxidized anti-Her3 antibody of SEQ ID NO: 03 and 04, and a relative retention time on the heparin affinity chromatography column is less than 0.87 times the retention time of an anti-pTau antibody of SEQ ID NO: 01 and 02.
