Introduction:

Protein A is a cell wall protein deriving from Staphylococcus aureus which exhibits unique binding properties for IgG from a variety of mammalian species and for some IgM and IgA as well. It binds with the Fc region of immunoglobulins preferentially through interaction with the heavy chain. It is conjugated to a wide variety of reporter molecules including fluorescent dyes, enzyme markers, biotin, colloidal gold and radioactive iodine for use in immunology and other biological research without affecting the antibody binding site.

It is also immobilized onto solid supports such as agarose beads for total IgG purifying from ascitic fluid, serum, culture supernatants and cell extract or interest protein.
