Description_x000D_ General description_x000D_ IgG antibody consists of four subclasses : IgG1, IgG2, IgG3 and IgG4. The IgG structure possesses four polypeptide chains containing two identical γ heavy (H) chains and two identical κ or λ light (L) chains of 50 kDa and 25 kDa respectively. The chains are interlinked with a disulfide bond._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 (whole molecule)-FITC antibody is specific for mouse IgG. Goat anti-mouse IgG is conjugated to Fluorescein Isothiocyanate (FITC), Isomer I. Following conjugation, unbound FITC is removed by extensive dialysis._x000D_ Immunogen_x000D_ Purified mouse IgG_x000D_ Application_x000D_ Anti-Mouse IgG (whole molecule)−FITC antibody produced in goat has been used in flow cytometry._x000D_ The antibody may be used for immunofluorescent staining of mouse spleen cells at a working dilution of 1:64. A working antibody dilution of 1:40 was used to stain the conidia of Botrytis cinerea for immunofluorescence. The antibody was also used for immunofluorescence of primary luteal cell cultures incubated with primary antibody against CD45 and rhizoids of Chara globularis incubated with anti-human spectrin antibody._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_ Packaging_x000D_ 0.5 mL in glass insert_x000D_ 1, 2 mL in glass bottle_x000D_ Biochem/physiol Actions_x000D_ IgG (immunoglobulin G) antibody has its function similar to IgM antibody in complement system activation. IgG participates in hypersensitivity type II and type III. It helps in opsonization, complement fixation and antibody-dependent cell-mediated cytotoxicity.
