説明

Bovine IgG 2 showed adsorption to Protein A-Sepharose CL-4 B column but not IgG 1. Carbethoxylation of histidyl residues in IgG 2 by diethylpyrocarbonate resulted in the loss of its binding ability to Protein A. The number of histidyl residues carbethoxylated was 4.2 to 8.3 per IgG 2 molecule. Upon removal of the carbethoxyl groups by hydroxylamine, the IgG 2 molecule thus decarbethoxylated recovered its binding ability to Protein A. Therefore, it is concluded that histidyl residues in IgG 2 molecules is important for the interaction between IgG 2 and Protein A.
