  • Publication number: 20120301923
    Abstract: The present disclosure provides systems and methods of using a semipermeable membrane in a dialysis fermenter as a separation layer between a cell-containing liquid culture medium and a non-cell-containing dialysis medium. In some embodiments, the semipermeable membrane may have a molecular cut-off of 15 kDa to 50 kDa. The instant disclosure also provides a dialysis fermenter with compartments for cell-containing culture medium, non-cell-containing nutrient solution as well as an exchange unit having a semipermeable membrane, wherein mass transfer takes place between the culture medium and the dialysis medium by means of diffusion and/or ultrafiltration. Methods for culturing cells are also disclosed.
