Recombinant Staphylococcal 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.
