Growth and productive characteristics of monoclonal cell lines based on CHO cells and producing a therapeutic protein have been monitored using the robot Ambr Tap Biosystems, which permitted to identify the leading line. Twenty four clones producing a recombinant monoclonal antibody were studied under the close to industrial conditions in a fed-batch culturing mode. The ambr®15 cell culture workstation controls 24 disposable mini bioreactors, and offers parallel processing and evaluation of multiple (24) experiments in an automated bench-top system. The volumetric productivity of 24 clones determined by ELISA was 120-450 mg /L. A protocol was shown to select a leader among producing clones for further research.
