  • Patent number: 8765415
    Abstract: The present invention provides a method of increasing protein production in a cell culture by growing cells that produce the protein (e.g., the growth phase) in a perfusion cell culture to a high cell density (i.e., at least above about 40×106 cells/N mL) and then switching to a protein production phase, wherein the cells are cultured in a fed-batch cell culture. The present invention further provides a method for clarifying a protein from a cell culture by adjusting the pH of the cell culture to below neutral pH (i.e., below a pH of 7) and settling the cell culture, such that the cell culture separates to form a supernatant layer and a cell-bed layer, wherein the protein is in the supernatant layer.

  • Publication number: 20140106405
    Abstract: The present invention describes methods and processes for the production of proteins by animal cell or mammalian cell culture. In one aspect, the methods comprise the growth of cells in a growth factor/protein/peptide free medium. In another aspect, the methods comprise the addition of growth factors during the production phase. The methods sustain a high viability of the cultured cells, and can yield an increased end titer of protein product, and a high quality of protein product.

  • Publication number: 20130155818
    Abstract: In a method for controlling an alarm function of an electronic device, an alarm time, an alarm mode, a plurality of control modes of the alarm function and a shaking frequency and an audio file corresponding to each of the control modes are set. If a current time matches the alarm time, the alarm function is started by activating the alarm mode and a monitor unit is enabled to monitor acceleration values of the electronic device. A first shaking frequency in a first predetermined time limit is recorded according to the acceleration values. The control mode corresponding to the first shaking frequency is confirmed, and the audio file corresponding to the confirmed control mode is output. The method further controls the alarm function according to the confirmed control mode.
