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 defense of the neonate against infections.
Anti-Mouse IgG (whole molecule)-TRITC antibody is specific for mouse IgG and all subclasses, it cross reacts with mouse IgA and IgM. Antibody purification is by ion exchange chromatography after which it is conjugated to crystalline tetramethylrhodamine isothiocyanate (TRITC).
Digestion of IgG by papain results in generation of fragment antigen binding (Fab) comprising one complete L chain and a variable and CH1 region of H chain. Pepsin digestion of IgG results in fragment crystallizable (fc), comprises the H chain constant region.', 'Immunoglobulin G (IgG) is a glycoprotein antibody th at regulates immune responses such as phagocytosis and is also involved in the development of autoimmune diseases . Mouse IgGs have four distinct isotypes, namely, IgG1, IgG2a, IgG2b, and IgG3. IgG1 regulates complement fixation in mice .
