摘要： A method includes measuring, by a flow sensor (70), a flow rate of a permeate fluid (48) flowing through a filter (20) of a membrane filtration system (12). Further, the method includes receiving, by a control unit (86), the measured flow rate of the permeate fluid (48) and determining, by the control unit (86), a first flux rate of the filter (20) based on the measured flow rate of the permeate fluid (48). Furthermore, the method includes comparing, by the control unit (86), the determined first flux rate with a first predetermined flux rate. Additionally, the method includes operating the membrane filtration system (12), by the control unit (86), in a normal mode or a flux tolerant mode based on the comparison of the determined first flux rate with the first predetermined flux rate. The flux tolerant mode of the membrane filtration system (12) is further based on a determined normalized water permeability value of the filter (20).

摘要： The present disclosure relates to a method for targeted integration of a donor vector into a specific pre-defined genomic location of an isolated eukaryotic host cell. The vector and host cell together comprise nucleic acid components allowing for the selection of cells having integrated the donor vector into the pre-defined genomic location of the host cell. In addition, it provides for the identification of any random integrations of the donor vector(s) into other parts of the host cell genome. Once identified, such cells present an excellent alternative for subsequent recombinant protein production.
