WebChanges in the affinity of IgGs to FcRn lead to changes in the half-life of engineered IgGs and Fc fusion proteins. Longer half-life of therapeutic antibodies means lower dose and longer interval between administering. For some diagnostic agents including imaging or radio-labeled agents a shorter half life in circulation results in lower non ... WebJan 22, 2024 · The introduction of histidine substitutions into its CDRs allowed pH-responsive antigen-binding leading to enhanced C5 clearance and prolonged half-life of the antibody. Moreover, additional mutations engineered in Fc-region enhanced the binding of the antibody to FcRn [ 27 ].
