Maternal IgG is transferred to fetus through the placenta that is vital for immune defence of the neonate against infections._x000D_ Human myeloma IgG2, λ is purified from human plasma by fractionation, ion-exchange and affinity chromatography procedures._x000D_ Application_x000D_ The purified IgG2, 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. Human myeloma IgG2, λ was used to check the efficiency of hydrophobic interaction membrane chromatography (HIMC)._x000D_ Physical form_x000D_ Solution in 0.02 M Tris buffered saline, pH 8.0._x000D_ Analysis Note_x000D_ The purity and identity are determined by immunoelectrophoresis, indirect ELISA, and SDS-PAGE._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.
