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.
A serum-free cell culture medium composition comprising a microsuspension comprising a mixture of a labile component and an antioxidant that is microencapsulated into a bead with a capsular matrix, wherein the bead has a diameter within the range of 0.05-1.5 mm, wherein a powdered cell culture medium is used for the microencapsulated microsuspension, wherein the composition is irradiated with gamma-rays, and wherein the labile component is embedded in the anti-oxidant to protect the labile component by reducing the impact of oxidation species generated during irradiation.
