2. It has been established that the so-called ‘ ZZ domain’, a synthetic IgG binding protein derived from tandem repeats of the B domain of protein A, interacts with the Fc portion of IgG molecules. HOW would you confirm that this ‘ ZZ domain’ indeed binds to the Fc region of IgG and not to that of IgM or IgE a.What would you establish as criteria for physiologically relevant binding of this ZZ domain to IgG Fc portion? b.What would...
