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._x000D_ There are four classes of IgG namely IgG1, IgG2, IgG3, and IgG4. Among them IgG1 is the most abundant antibody._x000D_ Specificity_x000D_ Binds all rabbit Igs._x000D_ Immunogen_x000D_ Purified rabbit IgG_x000D_ Application_x000D_ Anti-Rabbit IgG (whole molecule)-FITC antibody produced in goat has been used in immunohistochemistry and indirect immunofluorescence._x000D_ Physical form_x000D_ Solution in 0.01 M phosphate buffered saline, pH 7.4, with 15 mM sodium azide as a preservative._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) provides protection from infections caused by bacteria, fungi and viruses. Maternal IgG is transferred to fetus through the placenta that is vital for immune defense of the neonate against infections. IgG1 deficiency results in hypogammaglobulinemia. IgG2 deficiency increases susceptibility to bacterial infections IgG3 mediates effector functions IgG4 are associated with asymptomatic infection. IgG antibody have enormous therapeutic potential and the Fc region is involved for the development of therapeutic antibody._x000D_ Other Notes_x000D_ Antibody adsorbed with human IgG._x000D_ Preparation Note_x000D_ Adsorbed to reduce background staining with human samples.
