Technical grade IgG may be used as an economical alternative to the reagent grade immunoglobulins in applications where high purity is not required. IgG from mouse serum was used as negative control in immunohistochemistry at a concentration of 2 μg/ml. It was used as irrelevant control in chromatin immunoprecipitaion assay (10 μg).
Purified mouse IgG may be used as a reference antigen, standard, blocking agent, or coating protein in a variety of immunoassays including ELISA, dot immunobinding, Western immunoblotting, immunodiffusion, and immunoelectrophoresis. Other applications include starting materials for the preparation of immunogens and solid phase immunoadsorbents. Mouse IgG was used as standard in ELISA and chromatin immunoprecipitation assay. It was used to coat nano particles in the development of biosensors.
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
Mouse IgG is purified from normal mouse serum by fractionation and ion-exchange chromatography.
Immunoglobulin G (IgG) participates in hypersensitivity type II and type III reactions. IgG helps in opsonization, complement fixation and antibody dependent cell mediated cytotoxicity.
