Investigation of the binding site of mouse IgG subclasses to homologous peritoneal macrophages.
The binding of mouse myeloma IgG1, IgG2a, IgG2b, IgG1 Fc, IgG2b Fc and a pepsin produced C-terminal subfragment of IgG1 Fc and IgG2b Fc (provisionally identified as pFc') to mouse peritoneal macrophages was investigated. The high affinity cytophilic antibodies belonged to IgG2 subclasses and the binding site of these antibodies was located in the CH3 homology region.
