Biochem/physiol Actions

EnPresso® Y Defined is a pre-sterilized growth system designed to increase the yield of functional proteins expressed in Pichia pastoris when using AOX promoters. The system provides stress-free conditions, faster growth and eliminates the need for time-consuming media changes required when using conventional methanol-induction. EnPresso® growth systems provide optimal conditions for growth, metabolism and protein expression in microbial cultures. Protein yields are increased by enabling cultures to reach far higher cell densities than those achieved using conventional media.

By controlling growth rate and metabolism, a greater proportion of expressed protein can be correctly folded to improve solubility, minimize the risk of inclusion body formation, and ensure functionality of the final product.

EnPresso® growth systems maintain pH, provide adequate minerals, vitamins and trace elements to support growth, and use proprietary EnBase technology to ensure a constant, slow release of glucose from a polysaccharide substrate.
