Target Details

Target: IgG1 Fc

Background: Immunoglobulins are membrane-bound or secreted glycoproteins produced by B lymphocytes. IgG antibodies protect the body against the pathogens by agglutination and immobilization, complement activation, toxin neutralization, as well as the antibody-dependent cell-mediated cytotoxicity. IgG1 is most abundant in serum among the four IgG subclasses (IgG1, 2, 3 and 4) and binds to Fc receptors on phagocytic cells with high affinity. IgG comprise two identical light (L) and heavy (H) chains forming a 'Y-shaped' structure. It also is digested by pepsin proteolysis into two distinct fragments (Fab, Fc). Fc fragment is a homodimeric glycoprotein with one monomer consisting of two constant immunoglobulin domains (CH2, CH3) from the C-terminal half of one heavy chain. Through interaction with its ligands (FcγR, C1q and FcRn) it mediates various immune effector functions and increases the half-life of the antibody molecule. Recombinant IgG Fc is suggested to represent a potential anti-inflammatory drug for treatment of human autoimmune diseases. Recombinant human IgG1 Fc was expressed in HEK293 cell and purified by using conventional chromatography techniques.
