Description
General description
Antibody format: IgG
Immunoglobulin G (IgG) belongs to the immunoglobulin family. It is widely expressed and consists of a gamma heavy chain in the constant (C) region. IgG is a monomer with a molecular weight of about 150 kDa. The structure of IgG constitutes two identical heavy chains and two identical light chains with molecular weight of 50 kDa and 25 kDa respectively. The primary structure of this antibody also contains disulfide bonds involved in linking the two heavy chains, linking the heavy and light chains and resides inside the chains. IgG is further subdivided into four classes namely, IgG1, IgG2, IgG3, and IgG4 with different heavy chains, named γ1, γ2, γ3, and γ4, respectively. Limited digestion using papain cleaves the antibody into three fragments, two of which are identical and contain the antigen-binding activity. The third fragment does not possess antigen-binding activity and is known as fragment crystallizable (Fc). It interacts with cells and effector molecules. The Fc fragment contains the CH2 and CH3 domains of the antibody molecule. Maternal IgG is the only antibody transported across the placenta to the fetus. It passively immunizes the infants.
Immunogen
Human IgG F(c) fragment
Application
Anti-Human IgG (Fc specific)-Biotin antibody produced in goat (highly cross adsorbed) has been used in immunohistochemistry and for binding detection in ligand binding assay.
Biochem/physiol Actions
This product was prepared from monospecific antiserum by immunoaffinity chromatography using Human IgG coupled to agarose beads followed by solid phase adsorption(s) to remove any unwanted reactivities. Assay by immunoelectrophoresis resulted in a single precipitin arc against Anti-Biotin, Anti-Goat Serum, Human IgG, Human IgG F(c) and Human Serum. No reaction was observed against Human IgG F(ab′)2or Mouse serum proteins.
