Production instability currently limits the use of mammalian cells for industrial production of therapeutic proteins. We have previously reported that the loss of productivity in recombinant monoclonal antibody producing Chinese Hamster Ovary (CHO-mAb) cell lines is mainly due to a decrease in heavy chain (HC) and light chain (LC) transcripts. Molecular analysis indicates that the decreased mRN...

Additionally, they affect greatly work productivity, not only by eliminating patients in productive age from the working population, but also influencing every-day work performance. The productivity loss, which is significant from the individual’s perspective, can also be measured globally as ...
