    摘要: The present invention relates generally to nutritive medium, medium supplement, media subgroup and buffer formulations that contain lipid. Specifically, the present invention provides powder nutritive medium, medium supplement and medium subgroup formulations, particularly 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 including lipid components that facilitate the in vitro cultivation of cells. The invention is particularly directed to methods of production of these 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. The invention also relates to methods of producing sterile powdered media, media supplement (particularly powdered sera such as powdered FBS, powdered transferrin, powdered insulin, powdered organ extracts (such as bovine brain or pituitary extracts), powdered growth factors (such as EGF, FGF, etc.) and the like), media subgroup and buffer formulations. In a particularly preferred aspect, the invention relates to such methods wherein the sterilization is accomplished by gamma irradiation. The invention also relates to media, media supplement, media subgroup and buffer powders produced by these methods.

    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, 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.

    摘要: An apparatus and method for delivering oxygen to a cell culture medium is disclosed. In one embodiment, the apparatus includes a transfer chamber placed within the cell culture medium. The transfer chamber is adapted to allow the cell culture medium to come in substantial contact with a liquid chemical that is passing through transfer chamber. The apparatus further includes a vessel placed outside the cell culture medium that serves to contain and continually recharge the liquid chemical. The apparatus further includes a plurality of pumps and tubes for circulating the liquid chemical through the transfer chamber and back to the vessel. When the liquid chemical comes into contact with the cell culture medium, oxygen is transferred from the liquid chemical to the cell culture medium.
