人IgG3-λ，IgG3, Lambda from human myeloma plasma；purified immunoglobulin, >90% (microfluidic capillary gel electrophoresis)

Identity of IgG3, lambda light chain is verified by subclass monoclonal antibodies and type specific polyclonal antibodies in immunoelectrphoresis and indirect ELISA assays.

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.[1] IgG3 is the has a unique extended hinge region conferring greater flexibility
IgG3, λ from human myeloma plasma is purified by fractionation, ion-exchange and affinity chromatography.

Mammalian immunoglobins contain either lambda or kappa light chains.

 

IgG3, lambda light chain may be used as an antigen for the production and evaluation of antibodies developed for the indentification and classification of IgG3 subtypes. The purified IgG3, lambda 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 immunoblotting, immunodiffusion, immunoelectrophoresis, hemagglutination, and cell-binding assays.

The purified IgG3, 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 immunoblotting, immunodiffusion, immunoelectrophoresis, hemagglutination, and cell-binding assays.

 

Solution in 20 mM tris buffered saline, pH 8.0.

 

The purity and identity are determined by immunoelectrophoresis, indirect ELISA, and SDS-PAGE.
