Method for determining process variables in cell cultivation processes

High throughput cultivation systems are used in pharmaceutical research and development. In this connection, samples are taken and analyzed for important parameters using external analysis. The results of the analysis serve to assess the cultivation process and provide important information about the process. Especially with cultivations carried out in parallel, the manual effort of sample preparation is great and can lead to errors. In order to avoid the need for sampling and thus to minimize the errors, a method is described in the present patent application which makes desired target parameters accessible in the form of soft sensors by means of previously recorded process variables. Herein is described a method for determining process-relevant parameters in CHO processes (Chinese hamster ovary) in high- throughput cultivations, in particular glucose, lactate and the live cell density or the live cell volume.
