  • Publication number: 20240117401
    Abstract: Methods for adjusting the pH of a cell culture medium, methods for culturing cells in a pH-adjusted cell culture medium, and methods for making a polypeptide expressed by cells cultured in a pH-adjusted cell culture medium are described. Also described are systems for determining how much acid or base should be added to a cell culture medium to obtain a desired pH. The methods include a charge balance model that includes parameters for a functional relationship between a concentration of dissolved carbon dioxide in the cell culture medium, a mole fraction of gaseous carbon dioxide applied to the cell culture medium, a concentration of net medium acids in the cell culture medium, and the desired medium pH.

  • Publication number: 20120156763
    Abstract: An apparatus and methods for using biological material to discriminate an agent. In one embodiment of the present invention, the method includes the steps of providing at least one cell, exposing at least one cell to an agent, measuring the response of the cell to the agent in terms of a physical quantity related to at least one of the cellular physiological activities of the cell, and identifying the agent from the measured response. The method further includes the step of quantifying the agent from the measured response.

  • Patent number: 7704745
    Abstract: An apparatus and methods for monitoring the status of a cell that consumes oxygen. In one embodiment of the present invention, the method includes the steps of confining the cell in a sensing volume, measuring dynamically intracellular or extracellular signaling of the cell, and determining the status of the cell from the measured intracellular or extracellular signaling of the cell.
