产品特性
- Human IgG4 Fc is the tail region of the immunoglobulin G4 (IgG4) that interacts with cell surface receptors called Fc receptors and some proteins of the complement system. The ~230 amino acid fragment generally exists as a dimer, although under reducing conditions, it exists as a monomer. It is the basis of prolonged pharmacokinetics of antibodies and is commonly used as a fusion to extend half-life of fusion proteins. IgG4's hinge is shorter than that of IgG1, its flexibility is intermediate between IgG1 and IgG2 and some rotation may occur around the glycine residue in its hinge region.
