General description

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, Immunoglobins have two heavy (H) and two light (L) chains, linked by disulphide linkages. Each light chain comprises one variable N-terminal region and a constant C-terminal region. Heavy chain has one variable N-terminal region and three or four constant (CH1-CH4) C-terminal region. The four classes of IgG can be IgG1, IgG2, IgG3, and IgG4. IgG antibody 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. Rat IgG is purified from pooled normal rat serum by fractionation and ion-exchange chromatography.

Application

IgG from rat serum has been used:
  • in immunolabeling
  • in flow cytometry
  • in enzyme linked immunosorbent assay
  • as a control in neutrophil depletion assay
Purified rat 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. Rat IgG was used as isotype control in flow cytometry and injected into mice to induce tolerance against rat IgG.

Biochem/physiol Actions

IgG antibody have enormous therapeutic potential and its fragment crystallizable (Fc) region contributes for the development of therapeutic antibody.
