ST Cell Serum-Free Medium with Phenol Red and Glutamine

CCM-SF-0049 is a liquid serum-free medium developed for ST cell culture applications that require defined handling, lot documentation, and predictable supply. The medium contains phenol red for visual pH monitoring, D-glucose as a carbohydrate source, 4 mM L-glutamine, and 2 mM L-alanyl-L-glutamine. The supplied specification lists the product classification as animal origin, so users should qualify it according to their internal raw-material risk assessment and process requirements.

Key release parameters include pH 7.0–7.4 and osmolality 270–340 mOsmol/kg, which are relevant for process transfer, incoming quality review, and comparability studies. The medium is sterile-filtered and has an endotoxin specification of ≤3 EU/mL. It is intended for controlled laboratory and bioprocessing environments using ST cells under 37 °C and 5–10% CO2 culture conditions. For pricing coordination, volume planning, or project-specific documentation, procurement teams can use the request quote workflow.

• Serum-free expansion and maintenance of ST cells in flasks, bottles, and compatible scale-up formats.
• Process development studies where phenol red, glutamine, and L-alanyl-L-glutamine are required in the base formulation.
• Biopharmaceutical research workflows involving ST cell substrates, media screening, and raw-material comparability.
• Small-batch and pilot-scale culture work requiring defined pH, osmolality, endotoxin, and sterility specifications.
• Academic, biotechnology, and contract research use where a 500 mL liquid format simplifies media qualification and inventory control.

Store CCM-SF-0049 at 2–8 °C protected from light. Do not expose the bottle to unnecessary warming, repeated temperature cycling, or prolonged room-temperature hold times during routine use. The specified shelf life is 12 months when stored as recommended and kept within validated inventory controls. Shipments are packed on blue ice to support cold-chain handling during transit. Before use, inspect the container, label, and solution appearance, and apply aseptic technique when connecting, aliquoting, or transferring the medium into culture vessels.

CellCultureMedia supplies CCM-SF-0049 for research and bioprocess customers requiring traceable product specifications and procurement-ready documentation. Manufacturing and release controls are managed using ISO-aligned quality practices, with sterility, endotoxin, pH, osmolality, shelf-life, storage, and shipping specifications available for technical review. A Certificate of Analysis can be requested for applicable lots through our quality documentation channel. Free worldwide shipping is available where lane, package configuration, and import conditions permit, and bulk supply can be quoted for recurring programs.
