Praesto AC is a Protein A resin designed for high productivity, cost-effective MAb capture. It combines good capacity, excellent pressure/flow performance and NaOH CIP stability for up to 20 cycles, meeting common requirements for production PI and PII clinical trial materials. Praesto AC can also be used in small scale MAb purification, purification of MAbs for diagnostics, in process development and in pre-clinical processes.
