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 (ADCC). IgG tetramer contains two heavy chains (50 kDa ) and two light chains (25 kDa) linked by disulfide bonds, that is the two identical halves form the Y-like shape. IgG is digested by pepsin proteolysis into Fab fragment (antigen-binding fragment) and Fc fragment (\"crystallizable\" fragment). IgG1 is most abundant in serum among the four IgG subclasses (IgG1, 2, 3 and 4) and binds to Fc receptors (FcγR ) on phagocytic cells with high affinity. Fc fragment is demonstrated to mediate phagocytosis, trigger inflammation, and target Ig to particular tissues. Protein G or Protein A on the surface of certain Staphylococcal and Streptococcal strains specifically binds with the Fc region of IgGs, and has numerous applications in biotechnology as a reagent for affinity purification. Recombinant IgG Fc Region is suggested to represent a potential anti-inflammatory drug for treatment of human autoimmune diseases.\u003c\/p\u003e\n\n\u003cp\u003eAlternate Names: Ig gamma-2 chain C region, IgG2 Fc\u003c\/p\u003e\n\n\u003cp\u003eDescription: Recombinant Human Ig Gamma-2 Chain C Region is produced by our Mammalian expression system and the target gene encoding Val104-Lys326 (Val161Met, Ser257Ala) is expressed.\u003c\/p\u003e\n\n\u003cp\u003eAccession: P01859\u003c\/p\u003e\n\n\u003cp\u003eMolecular Weight: 25.1 KDa\u003c\/p\u003e\n\n\u003cp\u003eApparent Molecular Weight: 32 KDa, reducing conditions\u003c\/p\u003e\n\n\u003cp\u003eStorage Condition: Lyophilized protein should be stored at \u0026lt; -20°C, though stable at room temperature for 3 weeks.
