Praesto AP is a Protein-A resin designed on a novel, high-flow agarose backbone, which addresses today s late stage clinical manufacturing challenges for high productivity, together with cost effective MAb capture. It 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.
