Description_x000D_ General description_x000D_ Immunoglobulin G (IgG) belongs to the immunoglobulin family and is a widely expressed serum antibody. An immunoglobulin has two heavy chains and two light chains connected by a disulfide bond.It mainly helps in immune defense. It is a glycoprotein.IgG is a major class of immunoglobulin.Mouse consists of five immunoglobulin classes- IgM, IgG, IgA, IgD and IgE. Mouse IgG is further divided into five classes- IgG1, IgG2a, IgG2b and IgG3._x000D_ Immunoglobulin G (IgG) is a glycoprotein antibody that regulates immune responses such as phagocytosis and is also involved in the development of autoimmune diseases . Mouse IgGs have four distinct isotypes, namely, IgG1, IgG2a, IgG2b, and IgG3. IgG1 regulates complement fixation in mice ._x000D_ Immunogen_x000D_ Purified mouse IgG_x000D_ Application_x000D_ Anti-Mouse IgG (Fc specific) F(ab′)2 fragment antibody produced in goat has been used in CD117/Sca-1 fluorescence-activated cell sorting (FACS) analysis and to detect bound factor H in factor H binding assay._x000D_ Physical form_x000D_ Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 0.05% sodium azide._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Biochem/physiol Actions_x000D_ Immunoglobulin G (IgG) participates in hypersensitivity type II and type III reactions. IgG helps in opsonization, complement fixation and antibody dependent cell mediated cytotoxicity._x000D_ Other Notes_x000D_ Antibody adsorbed with bovine, equine and human serum proteins_x000D_ Preparation Note_x000D_ Adsorbed to reduce background with bovine, equine, or human samples._x000D_ Useful when trying to avoid background staining due to the presence of Fc receptors.
