Answer:No. It is dry medium powder for preparing a nominal 10 L volume.
Answer:Chinese hamster ovary (CHO) cells in fed-batch culture.
Answer:No. It is the EX-CELL Advanced CHO Fed-Batch basal medium, distinct from associated feed products.
Merck EX-CELL Advanced CHO Fed-Batch Medium is a chemically defined, serum-free powder medium for cultivating Chinese hamster ovary cells in fed-batch bioprocess development. The 10 L configuration contains approximately 0.221 kg of dry medium, sufficient to prepare a nominal 10 liters when reconstituted at the specified formulation concentration. The medium supports cell growth and recombinant protein production in processes where feed strategy, nutrient availability and product quality attributes require coordinated control. It is a basal culture medium and should be used with an appropriately designed nutrient feeding schedule rather than treated as a concentrated feed additive. Reconstitution involves suitable water quality, mixing and controlled preparation procedures, followed by the relevant filtration and quality checks. During cell-culture runs, monitor viability, metabolites, osmolality and product titer to guide process adjustments. The supplied item is dry powder, not a ten-liter ready-to-use liquid container and not an animal-serum supplement.
