About

BioProduction by SEKISUI describes SEKISUI’s contract service offering as a microbial focused CDMO with expertise in proteins and downstream purification. Our fermentation process development and production experience helps smooth technical transfer and process scale up. Our core competencies include E.coli and yeast fermentation, plant protein extraction, large scale bioprocessing, protein purification, bulk formulation, lyophilization and analytical testing. Our production site in the UK has been a leader in the manufacturing of high-quality proteins and specialty biochemicals globally to the healthcare market for over 40 years. We have worked with many global partners to supply high quality materials for a variety of applications, including proteins for biotherapeutics, pharmaceuticals, and diagnostic medical devices. About SEKISUI SEKISUI Medical Group is a diverse, global network consisting of a diagnostics business and pharmaceutical sciences business which spans drug development services and manufacturing, including active pharmaceutical ingredients and pharmaceutical intermediates, amino acids, as well as a wide range of enzymes for use in diagnostics, and biopharmaceutical contract manufacturing and more BioProduction by SEKISUI is a trusted provider of specialized CDMO services, offering biomanufacturing solutions built on decades of experience in microbial fermentation and downstream processing. We support the full development lifecycle—from strain optimization to clinical-scale manufacturing—catering to a wide range of biologics including enzymes, recombinant proteins, antibody fragments, viral vectors, and plasmids. Our microbial expertise spans multiple expression platforms including E. coli, Pichia pastoris, Bacillus, Streptomyces, Streptococcus, fungi, and yeast, enabling highly flexible and efficient process development for biologics. Our advanced UK facility based in Kent is equipped for full spectrum biomanufacturing services and features: Fermentation capacity from 2 L R&D scale up to 5,000 L production Integrated protein expression services for high-yield production Advanced chromatography and purification suites End-to-end antibody production services Lyophilization and bulk formulation GMP-aligned systems under ISO 9001 and ISO 8 cleanroom classifications In-progress GMP plasmid manufacturing and clinical-grade expansion Environmental control and zero-emissions sustainability framework We also provide expert plasmid production for research and therapeutics, with growing capabilities in viral vector manufacturing for cell and gene therapy markets. As established recombinant protein manufacturers, we support custom expression and scale-up for diverse biopharmaceutical programs. In cell and gene therapy, SEKISUI is committed to enhancing the reliability, scalability, and efficiency of cell culture. Ceglu™, our lead technology, is a chemically defined, synthetic matrix that provides a stable, feeder-free environment for culturing stem cells (iPSCs, ESCs, MSCs). To accommodate diverse workflows, Ceglu™ is available in two formats: ready‑to‑use pre‑coated culture ware for research workflows, and an automation‑friendly coating solution for cell manufacturing workflows which can be precoated and sterilized onto closed systems or bioreactor consumables for seamless cell production. With a focus on advancing regenerative medicine, SEKISUI partners with service providers, biopharma organizations, bioprocessing innovators and academia to deliver solutions that meet the evolving needs of the industry.
