MabPlex Expands Contract Manufacturing Capacity in China

MabPlex International Ltd wished to establish contract manufacturing and service capacity in Yantai, China. The facility design needed to allow the production of monoclonal antibodies, recombinant proteins and ADCs. The company’s intention was to be a one-stop for biologics production allowing customer to move from gene sequence to cell line development to commercial productions with MabPlex’s CHO cell line platform in the shortest possible time but with a high quality and professional service. The “state-of-the-art” quality systems needed to meet the needs of the USA, EU & Chinese GMP requirements.

Integrated Solutions from Sartorius Stedim Biotech

The Integrated Solutions team from Sartorius Stedim Biotech supported MabPlex in the realization of their facility complex. MabPlex has worked successfully with Sartorius Stedim Biotech’s bioreactors for many years and were very confident of the company’s bioreactor technology and the ease with which it can be scaled-up. Sartorius supported MabPlex from an early stage in the project providing conceptual, basic and detailed engineering designs for the new facility. The collaboration between MabPlex and Sartorius was very successful with the Chinese company being highly appreciative of the responsiveness, engagement and expertise of the Integrated Solutions team. MabPlex valued the speed and quality of the service they received from the Integrated Solutions team and the quality and reliability of the technology Sartorius specified.

100% Cell Culture Success Rate

With the help of Sartorius, MabPlex was able to establish from scratch a GMP biologics production facility in just 18 months. The success rate of cell culture in the new single-use bioreactors is 100% and the contamination rate is 0%. The collaboration with Sartorius has allowed MabPlex to create a ‘state-of-the-art’ facility for monoclonal antibody, recombinant protein production and ADCs. It is extremely flexible and adaptable due to the extensive implementation of single-use technologies that reduce cross contamination risk and shorten production cycles.
