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 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
Human IgG is purified from normal human serum by precipitation and gel filtration techniques.


Purified human IgG has been used :-
  • as blocking antibody for flow cytometry
  • as negative control in chromatin immunoprecipitation assays
  • to precipitate IgG in human larynx epidermoid carcinoma cells by immunoprecipitation
  • as a standard in enzyme-linked immunosorbent assay

Biochem/physiol Actions

Immunoglobulin G (IgG) regulates the immune responses such as phagocytosis and is also involved in the development of autoimmune diseases. IgG1 regulates complement fixation in mice.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide

Specifically designed bionanoparticles with a function-oriented protein-coating layer interact with self-prepared receptor surfaces as the counterpart. Based on surface plasmon resonance biosensing experiments, a model framework is validated to estimate the number of bonds formed between these bionanoparticles and the...

B lymphocytes can suppress immunity through interleukin (IL)-10 production in infectious, autoimmune, and malignant diseases. Here, we have identified a natural plasma cell subset that distinctively expresses the inhibitory receptor LAG-3 and mediates this function in vivo. These plasma cells also...
