unusual facts about Fc region



Infliximab

Etanercept also binds and inhibits the action of TNF-α, but is not a monoclonal antibody (it is instead a fusion of TNF-receptor and an antibody constant region).

Single-chain variable fragment

Single-chain variable fragments lack the constant Fc region found in complete antibody molecules, and, thus, the common binding sites (e.g., Protein G) used to purify antibodies.

Type II hypersensitivity

These tagged cells are then recognised by natural killer cells (NK) and macrophages (recognised via IgG bound (via the Fc region) to the effector cell surface receptor, CD16 (FcγRIII)), which in turn kill these tagged cells.
