Abstract: The invention concerns a method for large-scale production of a polypeptide in eukaryote cells contained in a serum-free culture liquid, said method comprising (i) a propagation phase for said cells, where the cells are propagated in a first cell culture liquid, and (ii) a production phase for said cells, where the cells are present in a second cell culture medium liquid, wherein each of the cell culture liquids comprise a plant protein hydrolysate, and wherein the ratio between the concentration of the plant protein hydrolysate (C1) in the first cell culture liquid and the concentration of the plant protein hydrolysate (C2) in the second cell culture liquid is at least 1.5:1 (C1:C2).

Abstract: The invention provides a method for production of polypeptides in eukaryote microcarrier cell culture, the method comprising the steps of (i) Culturing cells expressing said polypeptide on microcarriers under conditions and at a setpoint temperature appropriate for expression of said polypeptide; (ii) Cooling the culture to a predetermined temperature below said setpoint; (iii) Sedimenting the microcarriers; and (iv) Harvesting all or part of the culture medium.

Abstract: The invention provides a method for industrial-scale production of FVII polypeptides in mammalian cell culture free of animal-derived components.

Abstract: The invention provides a method for large-scale production of a polypeptide, such as a Factor VII or Factor VIIa polypeptide, in eukaryote cells, such as mammalian cells, contained in a culture liquid, said method comprising: monitoring the concentration of dissolved CO2 in the culture liquid, and constantly or intermittently sparging atmospheric air through the culture liquid, wherein the sparging rate of the air is controlled in relation to the monitored concentration of dissolved CO2 in the culture liquid. The method reduces or eliminates the use of bases while providing an excellent pH control. The invention also provides a culture vessel suitable for the methods.

Abstract: The invention relates to methods for cultivating mammalian cells and for producing recombinant proteins in large-scale cultures of such cells. The proteins are, e.g., Factor VII or Factor VII-related polypeptides.
