Protein A is a cell wall protein derived from Staphylococcus aureus that exhibits unique binding properties for IgGs from a variety of mammalian species and for some IgM and IgA. It preferentially...
Streptavidin (SA) has a strong affinity with biotin. The affinity constant Kd can generally reach 10-15M. Active SA usually exists as a tetramer. Because SA does not contain glycosyl, SA has a lower...
