General description

Human IgG antibodies are primarily responsible for the facilitation of humoral immune responses such as complement fixation, placental transport, and phagocytosis among many others[1]. IgG from human serum can be used as an economical alternative for reagent grade immunoglobulins where high purity is not essential. It can also be used in immunoelectrophoresis. The product is reactive in humans.
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[2]
Human IgG is purified from normal human serum by fractionation.

Application

Purified human IgG may be used as a reference antigen, standard, blocking agent, or coating protein in a variety of immunoassays including ELISA, dot immunobinding, Western immunoblotting, immunodiffusion, and immunoelectrophoresis. Other applications include starting materials for the preparation of immunogens and solid phase immunoadsorbents. Technical grade human IgG may be used as an economical alternative to the reagent grade immunoglobulins, in applications where high purity is not required. IgG from human serum was used as ELISA standard in various studies.[3][4][5] A concentration range of 200 μg/ml to 1 mg/ml of human IgG was used for blocking in flow cytometry.[6][7][8]
