IPA 300S is a Repligen legacy Protein A affinity resin used in commercial manufacturing processes for therapeutic antibodies. This resin can also be used for bench-scale experiments and immunoprecipitation (IP) methods. IPA 300S incorporates Repligen's srPA50 ligand immobiized onto an agarose bead.
Please substitute all future orders for IPA300 with the equivalent product IPA300S.
IPA 400HC offers a higher performing Protein A resin with double the binding capacity and linear flow rate capability of IPA 300. This resin can be used for bench- to commercial-scale production of therapeutic and diagnostic antibodies. IPA 400HC incorporates animal-free recombinant Protein A ligand, srPA50, immobilized onto a highly cross-linked agarose bead.
