Human IgG

Human IgG purified protein (Immunoglobulin G) are antibody molecules. Human IgG is composed of four peptide chains — two heavy chains gamma and two light chains. Human IgG has two antigen binding sites. Other Immunoglobulins may be described in terms of polymers with the IgG structure considered the monomer. Human IgG typically constitutes 75% of serum immunoglobulins. Human IgG molecules are synthesized and secreted by plasma B cells. Human IgG whole molecule has been tested by SDS-Page and ELISA and can be utilized as a control or standard reagent in Western Blotting, Flow, and ELISA experiments.
