Protein A is a highly stable surface receptor produced by Staphylococcus aureus, which is capable of binding the Fc portion of immunoglobulins, especially IgGs, from a large number of species (Boyle and Reis, 1987).
Each protein A molecule can bind 2 molecules of IgG, allowing the formation of a precipitate (Sjöholm, 1975).
