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_ Specificity_x000D_ Anti-Mouse IgG (Fab specific)-FITC antibody is specific for Fab fragment of all mouse IgG subclasses. It shows no reactivity with mouse IgG, Fc fragment, or human IgG. Goat anti-Mouse IgG is conjugated to FITC and then purified by gel filtration to remove free FITC. The antibody is adsorbed with human IgG and rat serum proteins to ensure minimal cross reactivity._x000D_ Immunogen_x000D_ Purified mouse IgG_x000D_ Application_x000D_ Anti-Mouse IgG (Fab specific)-FITC antibody may be used for immunofluorescence of human peripheral blood lymphocytes at a minimum dilution of 1:64. It may be used for immunohistochemistry of formalin-fixed, paraffin-embedded human tonsil slides at a working antibody dilution of 1:200. For immunofluorescence, a working dilution of 1:200 was used in various studies. To study DNA synthesis in mouse two-cell stage embryos by BrdU antibody, mouse IgG (Fab specific)-FITC antibody dilution of 1:50 was used._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 human IgG and rat serum proteins._x000D_ Preparation Note_x000D_ Adsorbed to reduce background with human or rat samples
