    Abstract: 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. The 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.

    Abstract: 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, are described. Stability of the labile compound is increased either, by derivatization or by sequestering the labile compound. Sequestering can be done either by encapsulation within a microcapsule or by the use of sequestering agents. Encapsulation can provide controlled release of the susceptible compound being protected. These methods may improve or extend the storage conditions, the shipping and handling of media compositions comprising the labile compounds at room temperature rather than at lower temperatures, thereby decreasing shipping costs.

    Abstract: 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.
