Description_x000D_ General description_x000D_ Immunoglobulin G (IgG) contributes to 10-20% of plasma protein and is regarded as one of the most predominant serum protein. It consists of four subclasses: IgG1, IgG2, IgG3 and IgG4. The IgG structure possesses four polypeptide chains containing two identical γ heavy (H) chains and two identical κ or λ light (L) chains of 50 kDa and 25 kDa, respectively._x000D_ Application_x000D_ Anti-Bovine IgG (whole molecule)-FITC antibody produced in rabbit has been used in indirect fluorescent antibody test (IFAT)._x000D_ Physical form_x000D_ Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Biochem/physiol Actions_x000D_ IgG antibody subtype is the most abundant of 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 defense of the neonate against infections. The coupling of FITC to Anti- Bovine IgG (whole molecule) antibody allows for the visualization of protein by fluorescent microscopy.
