As the developer of high quality antibodies, we have extended our product portfolio by Protein A Agarose affinity resins.
Protein A is a cell wall protein from Staphylococcus aureus and is commonly used for the affinity purification or pull downs of IgG class antibodies. It binds to immunoglobulins through interaction with the IgG heavy chain within the Fc region. Antibodies from serum (polyclonal antibodies), ascites or cell culture supernatant of hybridoma cell lines (monoclonal antibodies) can thus be easily isolated.
Protein A does not bind to all IgG classes from all species equivalently well.
