Cell cultivation and production of recombinant proteins by means of an orbital shake bioreactor system with disposable bags at the 1,500 liter scale
InactiveUS20090233334A1High degreeEasy to handleMicroorganismsBiochemistry apparatusCulture cellBiology
The present invention provides a novel method for culturing cells as well as a novel method for producing a recombinant protein by culturing cells at large scale (up to 1,500 L nominal volume and 750 L working volume), whereby an inflated bag provides a sterile, disposable cultivation chamber. The inflated bag is partially filled with liquid cultivation media and cells, and placed into a containment vessel. The containment vessel is positioned onto an orbitally shaken platform. The orbital shaking moves the containment vessel and thus the bag and induces thereby motion to the liquid contained therein (“shake mixing”). This motion (caused by orbital shaking) induces a dynamic force field that ensures cell suspension, bulk mixing, and oxygen transfer from the liquid surface to the respiring cells without damaging shear or foam generation.

A system, method and computer program product for requirements management. Particularly, a requirements management scheme performs at least the following functions: 1) it guides a team through the requirements process and provides a structure for collecting “requests”. By using the scheme, team members are prompted to think about and record relevant information that will help clarify and complete requests; and, 2) the scheme allows users to use the attributes throughout the development process to identify risk and make improvements to their process. Many of these attributes can be refined during the development phase or even later. Besides helping team members achieve continuous improvement in their requirements process by providing a set of data and metrics for collection and assessment, the scheme enables an organization to effectively manage their requirements as well as manage changes to those requirements.

The invention discloses a device and method for generating vector ultrashort laser pulse at a middle-infrared band. Laser output at a middle-infrared corresponding wave band is achieved by a gain module taking a high-power and high-brightness pumping source and rare-earth ion-doped sesquioxide ceramic as a core component, output of pulse laser is achieved by a locked-mode component, output and control of a vector beam is achieved by a dual-refraction mode selection mechanism of an annular diaphragm, cavity non-linear management is achieved by a high non-linear medium, dispersion management isachieved by chirp mirror, and a round grating is used as a waveguide output coupling mirror to obtain an output of all-solid-state ultrafast laser at the middle-infrared band having vector characteristic. The obtained radial polarization vector beam at the middle-infrared band has a unique polarization singular point, the obtained pulse width is at optical period order, and the device has wide application in the frontier field such as high-precision laser medical operation, super-resolution imaging, quantum communication and attosecond light sources.
