Abstract excerpt
We have engineered a cysteine residue at position 442 (EU/OU numbering) in the third constant domain (C(H)3) of the heavy chain of several IgGs with different specificities, isoforms, and variants with the intent to introduce a site for chemical conjugation. The variants were expressed in NS0 mouse myeloma cells, where monomeric IgG is the major form and formation of aggregate was minimal. Monomeric IgG contained...
