Protein A and protein G are recombinant proteins that bind with high affinity to the Fc portion of several classes and subclasses of immunoglobulin (IgG´s) from a variety of species. Specific antigens are bound in a second step reversible towards the bound IgG. A following washing step and elution by pH shift generates the purified target protein under native conditions. MagSi protein A and G beads can be regenerated and reused several times (up to 10 times), incl large volume scales.
