Protein A Agarose Resin 4 Rapid consists of rProtein A covalently bound to highly crosslinked agarose beads. rProtein A has high affinity regions that are specially bonded to the Fc region of the immunoglobulins (especially IgGs of different species). Protein A agarose beads have been widely used to purify a wide range of immunoglobulins of different mammalian species and also to purify certain IgG subclasses that have no affinity. Bead Geometry & Size: Spherical, Standard: ~50-150um Crosslinked: Highly Crosslinked Agarose %: 4% Coupling Method: Covalent binding by reductive amination Static Binding Capacity: ~25mg human IgG/ml resin Antimicrobial Agent: 20% Ethanol Storage Temperature: 2-8C
