  • Patent number: 8911995
    Abstract: The invention provides a culture device comprising a plurality of culture units, wherein each unit comprises a culture chamber, an inlet port for liquid supply of the culture and an outlet port for discharging liquid from the unit, wherein the inlet port is in fluid communication with the culture chamber and the culture chamber is in fluid communication with the outlet port for allowing a liquid flow through the culture chamber. The culture device is particularly suitable for testing immune cells and immunofunction in vitro. Aspects of the invention include a culture device and associated methods for cultivating immune cells and an in vitro method of analysing the effect of a test compound on immune cells.
    Type: Grant

  • Publication number: 20090286317
    Abstract: The invention provides a culture system, which combines a device for undifferentiated proliferation of the cells with a device for cell differentiation and proliferation. Aspects of the invention include a modular culture system, a kit and an associated method for combining undifferentiated proliferation of cells with differentiation and proliferation of cells in a single, integrated device. The culture system has a first compartment comprising a plurality of miniaturized culture cavities that are sealed on one end by a surface that may be perforated, and a second compartment which defines one or more, larger culture chambers, and wherein said first and second compartment can be sterilely connected and living cell material can be transferred directly and in a controlled manner from the first compartment into the second compartment.

  • Publication number: 20050032127
    Abstract: The invention relates to a method for the non-invasive selection of single living cells under gentle conditions from mixtures of cells or cell cultures with respect to a specific production performance. To this end, the concentration of substances produced by the individual cells which become enriched at the cell membrane, such as reporter gene products (GFP) or specifically secreted products, such as antibodies, is determined by fluorescence-microscopic detection methods.
