Abstract
The present invention concerns a method for preparing antigen binding proteins with reduced viscosity. The method proceeds by replacing residues in high viscosity variable domain subfamilies with residues in correlating low viscosity subfamilies. The method further comprises substituting residues in the Fc domain with residues associated with low viscosity and adding charged residues to the C-terminus of the Fc domain. The present invention further concerns antigen binding proteins produced by this method.
