There are many types of buffers in the production process of monoclonal antibodies, they are updated quickly, and the requirements for control are particularly high. Therefore, the batch production process is adopted in the large-scale production of monoclonal antibody drugs, making it easier to achieve large-scale production of monoclonal antibodies. For the antibody process, Lisure has launched a DCS-structured chromatography system, buffer preparation system, concentrated buffer preparation tank, concentrated buffer storage tank and CIP station integrated control module, realizing one-click production and data integration of downstream processes.
