一般描述
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. IgG4 is the least abundant of the IgG subclass. IgG4-related systemic diseases include autoimmune pancreatitis, mediastinal fibrosis and multiple sclerosis.
Human myeloma IgG4, λ is purified from human plasma by fractionation, ion-exchange, and affinity chromatography procedures.
应用
The purified IgG4, λ may be used as an immunoglobulin calibrator, reference antigen, blocking agent, or coating protein in a variety of immunoassays including ELISA, dot blot immunobinding, Western immunobloting, immunodiffusion, immunoelectrophoresis, hemagglutination, and cell binding assays. Purified IgG4, λ was used as isotype control in flow cytometry of chronic lymphocytic leukemia and mantle cell lymphoma cells. It was also used for lectin- surface plasmon resonance and IgG subclass labelling by flow cytometry at a concentration of 50 μg/mL.
分析说明
The purity and identity are determined by immunoelectrophoresis, indirect ELISA, and SDS-PAGE.
