mRNA

Overview: WuXi Biologics’ services for mRNA therapeutics and vaccines

WuXi Biologics offers extensive development capabilities and GMP manufacturing capacity for mRNA therapeutics and vaccines. Our expert and highly-trained team provides end-to-end services from initial plasmid DNA manufacturing to drug substance (DS) and drug product (DP) GMP production. Our GMP facilities include a microbial-based manufacturing facility with up to 300L scale fermenter for plasmid DNA production, and multiple vessels covering a wide range of reaction volumes and purification equipment for mRNA transcription and purification. In addition, state-of-the-art mRNA-LNP production systems and robotic aseptic filling systems are available for DP manufacturing. As with all of our services, the foundation of our mRNA service platform is built upon our remarkable in-house, single-sourced CMC development and manufacturing capabilities and expertise, executional excellence, and world-class quality system.
