Analysis of split-peak data according to Eq. (12) for injections of rabbit immunoglobulin G (IgG) onto protein A columns prepared by various immobilization methods and supports. The conditions for each plot were as follows: Schiff base method, 500 Å pore size silica, 22 μg IgG (●); Schiff base method, 500 Å pore size support, 11 μg IgG (●); Schiff base method, 50 Å pore size support, 15 μg IgG (▲); carbonyldiimidazole method, 500 Å pore size support, 2.7 μg IgG (■); and ester/amide method, 500 Å pore size support, 8.2 μg IgG (◆).
