Description_x000D_ General description_x000D_ Immunoglobulin G (IgG) belongs to the immunoglobulin family and is a widely expressed serum antibody. It consists of a gamma (γ) heavy chain in the constant (C) region. The monomeric 150 kDa 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._x000D_ Application_x000D_ HRP-conjugated Anti-Rabbit IgG Concentrate (Item I1) has been used in Western Blotting and Immunohistochemistry._x000D_ Other Notes_x000D_ This item is for RAB series CBEL ELISA kits.
