WebDec 20, 2024 · The FcRn binding assay is also performed using a variety of tools such as SPR, BLI, and ELISA. An additional important technique that has been very popular in recent times for binding assays (both FcγR and FcRn binding) is that of amplified luminescent proximity homogeneous assay (ALPHA) ( 40, 41 ). 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]. WebThe neonatal Fc receptor (also FcRn, IgG receptor FcRn large subunit p51, or Brambell receptor) is a protein that in humans is encoded by the FCGRT gene.
