Anti-Human IgG (γ-chain specific)-Alkaline Phosphatase antibody is suitable for use in ELISA (at 1:2500 and 1:10,000 dilutions). The antibody can also be used for western blot (1:30,000) and immunohistochemistry (at 1:50 dilutions using formalin-fixed, paraffin-embedded sections).

Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.
Western Blotting (1 paper)

Proteins harvested from E. coli cultures were run on SDS-page gel for western blot analysis using alkaline phosphatase conjugated goat anti-human IgG (chain specific) at a concentration of 1:10000 for the secondary. IgG was detected in human serum by Elisa using alkaline phosphatase conjugated goat anti-human IgG (gamma-chain specific) diluted 1:5000 in 0.25% BSA/PBS. Assay was developed using p-nitrophenyl phosphate substrate (1mg/ml Sigma).

General description

Human IgGs are glycoprotein antibodies that contain two equivalent light chains and a pair of identical heavy chains. IgGs have four distinct isoforms, ranging from IgG1 to IgG4. These antibodies regulate immunological responses to allergy and pathogenic infections. IgGs have also been implicated in complement fixation and autoimmune disorders . Anti-Human IgG (γ-chain specific)-Alkaline Phosphatase antibody is specific for human IgG when tested against human IgA, IgG, IgM, and Bence Jones κ, and λ myeloma proteins.
