MicroProtein Technologies Inc. Recombinant Biologics

After years of proprietary research and development, MicroProtein Technologies Inc. has developed a robust solid media-based E. coli manufacturing platform, MPTxpress, which far surpasses conventional fermentation as a reliable and inexpensive way to produce recombinant proteins.

MPTxpress has advantages including higher yields with incredible simplicity and related cost savings, including no need for bioreactors, mixers, etc.; is fully singleuse; minimizes up-stream and down-stream processing; and eliminates the need for expensive fixed stainless steel equipment. E. coli is cultured on top of a membrane laid on top of 12-inch square agar plates, with harvesting involving scraping concentrated protein paste off the membrane. Each plate produces >1 gram of protein after incubation overnight at room temperature in a standard lab incubator. MPTxpress is scalable to commercial manufacture, e.g., ≥1 kg/day – simply use more trays (mini bioreactors in parallel)
