Description_x000D_ General description_x000D_ IgG antibody subtype is the most abundant serum immunoglobulins of the immune system. It is secreted by B cells and is found in blood and extracellular fluids and provides protection from infections caused by bacteria, fungi and viruses. Maternal IgG is transferred to fetus through the placenta that is vital for immune defence of the neonate against infections._x000D_ Immunoglobulin G (IgG) is a member of the immunoglobulin family and contains gamma (γ) heavy chain in the constant (C) region. Monomeric structure of IgG contains 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 implicated 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_ Specificity_x000D_ Binds all mouse Igs._x000D_ Useful when trying to avoid background staining due to the presence of Fc receptors. Anti-Mouse IgG (Fab specific) F(ab′)2 fragment-FITC antibody recognizes Fab fragment of mouse IgG. No cross reaction is observed with the Fc fragment of mouse IgG. No reactivity is observed with human, horse or bovine serum. The antibody is purified by affinity isolation and conjugated with FITC in an alkaline reaction._x000D_ Immunogen_x000D_ Purified mouse IgG; The F(ab′)2 fragment of the antibody is obtained from pepsin digested antiserum_x000D_ Application_x000D_ Anti-Mouse IgG (Fab specific) F(ab′)2 fragment−FITC antibody produced in goat has been used in:_x000D_ • flow cytometry for fluorescence-activated cell sorting (FACS) analysis_x000D_ • immunofluorescence and confocal microscopy_x000D_ • immunofluorescent HSP72 detection/immunocytochemistry experiments_x000D_ Physical form_x000D_ Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM 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. IgG2a has cytotropic properties and IgG2 molecules have the ability to activate the complement system._x000D_ Maternal IgG is transferred to fetus through the placenta that is vital for immune defence of the neonate against infections._x000D_ Other Notes_x000D_ Antibody adsorbed with bovine, equine and human serum proteins._x000D_ Preparation Note_x000D_ Adsorbed to reduce background staining with bovine, horse or human samples.
