Identification of a direct interaction between the Fab domains of IgG antibodies and human FcRn upon IgG-FcRn complex formation

Abstract IgGs have become successful drug scaffolds by combining specific target binding with the ability to induce cellular cytotoxicity. Furthermore, IgGs possess unusually long half-lives in the blood (2-3 weeks). IgGs achieve such extraordinary half-lives through a pH-dependent interaction with...
