Praesto AP is an agarose-based Protein A resin designed on a novel, high-flow matrix. It addresses today's clinical trial material demands for high productivity, together with cost effective MAb capture, and is purpose-designed and evaluated for the production of late-phase clinical trial material, PIII and commercial manufacture, where typically hundreds of reuse cycles are performed.
