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_ Anti-Mouse IgG (Fc specific) F(ab′)2 fragment−FITC antibody is specific for the Fc fragment of mouse IgG. No cross reactivity is observed with the Fab fragment of mouse IgG. Purified antibody is conjugated to fluorescein isothiocyanate (FITC) in an alkaline reaction and then purified to remove unbound FITC._x000D_ Specificity_x000D_ Binds mouse IgG; does not bind other mouse Igs._x000D_ Immunogen_x000D_ Purified mouse IgG_x000D_ Application_x000D_ Anti-Mouse IgG (Fc specific) F(ab′)2 fragment−FITC antibody may be used for immunohistochemistry at a working dilution of 1:320 using formalin-fixed, paraffin-embedded sections of human tonsil. Antibody dilution of 1:200 was used to label sections of human brainstems and cervical spinal cords with primary antibody against human Bcl-2 protein. The antibody was also used to label erythrocytes for photon reassignment microscopy and for FACS using melanoma cells._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_ 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.
