WebDec 1, 2024 · FcRn binds the IgG at the CH2–CH3 hinge regions in a pH dependent manner: binding occurs at slightly acidic pH (pH 6.0–6.5), whereas at neutral pH (pH 7.2–7.4) the Fc domain is released from the receptor. The interaction can be described by 2:1 stoichiometry, as FcRn binds to a single Fc fragment [ 17].
