摘要： The monitoring and control of bioprocesses is provided. The present disclosure provides the ability to generate generic calibration models, independent of cell line, using inline Raman probes to monitor changes in glucose, lactate, glutamate, ammonium, viable cell concentration (VCC), total cell concentration (TCC) and product concentration. Calibration models were developed from cell culture using two different CHOK1SV GS-KO™ cell lines producing different monoclonal antibodies (mAbs). Developed predictive models, qualified using an independent CHOK1SV GS-KO™ cell line not used in calibration, measured changes in glucose, lactate, ammonium, VCC, and TCC with minor prediction errors over the course of cell culture with minimal cell line dependence. The development of these generic models allows the application of spectroscopic PAT techniques in a clinical manufacturing environment, where processes are typically run once or twice in GMP manufacturing based on a common platform process.

摘要： A perfusion apparatus as disclosed for withdrawing a fluid medium from a bioreactor during the growth of a cell culture on microcarriers within the bioreactor. Also disclosed is a method for culturing cells in a bioreactor contained on microcarriers. The perfusion apparatus includes a hollow tubular member attached to a filter member. The filter member has a pore size and volume capable of withdrawing a fluid medium at a relatively high flow rate from the bioreactor.
