摘要： The present invention relates to nutritive medium, medium supplement, media subgroup and buffer formulations. The present invention provides powder nutritive medium, medium supplement and medium subgroup formulations, e.g., cell culture medium supplements (including powdered sera such as powdered fetal bovine serum (FBS)), medium subgroup formulations and cell culture media comprising all of the necessary nutritive factors that facilitate the in vitro cultivation of cells. The invention further provides powder buffer formulations that produce particular ionic and pH conditions upon reconstitution with a solvent. The invention provides methods for production of media, media supplement, media subgroup and buffer formulations, and also provides kits and methods for cultivation of prokaryotic and eukaryotic cells, particularly bacterial cells, yeast cells, plant cells and animal cells (including human cells) using these dry powder nutritive media, media supplement, media subgroup and buffer formulations.

摘要： The present invention provides a cell culture medium formulation that supports the in vitro cultivation, particularly in suspension, of mammalian cells, particularly epithelial cells and fibroblast cells, and methods for cultivating mammalian cells in suspension in vitro using these media. The present invention also provides chemically defined, protein-free eukaryotic cell culture media comprising an iron chelate and zinc, which is capable of supporting the growth (and particularly the high-density growth of mammalian cells) in suspension culture, increasing the level of expression of recombinant protein in cultured cells, and/or increasing virus production in cultured cells. The invention also provides kits for use in the cultivation of a mammalian epithelial cell that comprise one or more containers, wherein a first container contains the culture medium of the invention. These kits may further comprise one or more additional containers containing one or more supplements.

摘要： Compositions and methods are described for preparing media, feeds, and supplements. Such methods and medias may display increased stability of labile components and may use, for example, microsuspension and/or encapsulation technologies, chelation, and optionally, coating and/or mixing the labile compounds with anti-oxidants. The compositions may withstand thermal and/or irradiation treatment and have reduced virus number. These techniques may result in product with extended shelf-life, extended release of their internal components into culture, or in product that can be added aseptically into a bioreactor using minimal volumes. The compositions and methods may optimize the bioproduction workflow and increase efficiency.

摘要： Methods for increasing the stability of, or protecting, labile components such as ethanolamine, growth factors, vitamins, etc., in compositions such as a cell culture medium. Stability of the labile compound is increased either, by derivatization of the labile compound with chemicals, or by sequestering the labile compound. Sequestering can be done either by encapsulation within a microcapsule, or by the use of sequestering agents. Encapsulation includes the encapsulation of dendrimers complexes of susceptible compounds within the microcapsule, thereby providing the controlled release of the susceptible compound that was protected.
These methods may improve and extend storage conditions of compositions comprising the labile compounds, improve shipping and handling of compositions comprising the labile compounds, such as dry media formulations, at room temperature rather than at lower temperatures thereby decreasing shipping costs. Stabilization of labile compounds in compositions such as dry format media can be viewed as a contribution to green technology.-

摘要： The present invention is directed generally to dry cell culture media or feeds in pellet formats which can be reconstituted into liquid media for culturing cells in vitro. Each pellet composition may comprise the same or a different composition; for example, different vitamins, amino acids, buffers, trace salts, pH, iron chelators, etc. The invention also relates to methods of making dry cell culture media by altering ratios of different pellet compositions, or, methods of making modular dry cell culture media, or customizing media formulations for growing a cell type using pellets. According to the invention, media pellets may be easier to handle either before reconstitution, during shipping and handling; and/or during reconstitution. Media pellets may be used in any container like bags including sterile, single use bags for preparing media formulations. The invention also relates to kits and culture systems using media pellets.
