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
Goat IgG is purified from normal goat serum by fractionation.
Goat IgG is a glycoprotein antibody that is fractionated from pooled normal goat serum. In immunoelectrophoresis, goat IgG yields a single major arc of precipitation in the γ region against anti-goat IgG and anti-goat whole serum. Minor γ arcs may also be observed against anti-goat whole serum.

Technical grade IgG may be used as an economical alternative to the reagent grade immunoglobulins, in applications where high purity is not required. Goat IgG was used as negative control antibody in immunohistochemical staining of cecal tissue of pigs at a dilution of 1:56000. Goat IgG was used in immunohistochemistry of rat brain sections at a concentration of 2 μg/ml. The antibody was also used in chromatin immunoprecipitation and as control in infection inhibition assay.
In immunohistochemical applications, IgG from goat serum can be used as a blocking agent (500 μg/ml in paraformaldehyde-fixed mouse uterus sections) or as a negative control (1:56000 in pig cecal tissue).
