Serum-Free CHO Supplement Feed B, ADCF

This serum-free CHO supplement feed is an animal-origin-free liquid feed component for bioprocess development, clone screening, scale-down modeling, and fed-batch optimization. It is intended for use as a concentrated nutrient feed alongside compatible serum-free production media where additional carbon sources, amino acids, vitamins, salts, and process nutrients are required during extended culture. The product is classified under serum-free media and is suitable for procurement teams standardizing animal-origin-free raw materials across research and bioproduction programs.

CCM-SF-0036 is supplied in a 50 mL liquid format for convenient evaluation, media panel testing, and small-scale feeding studies. The product is sterile-filtered and specified with endotoxin at ≤20 EU/mL. Osmolality is controlled at 1000–1400 mOsmol/kg, reflecting its role as a concentrated feed rather than a complete growth medium. Recommended culture conditions are 37 °C with 5–10% CO2, aligned with common CHO suspension workflows. For volume planning, the listed unit price is $319.44, with bulk quotation available for multi-bottle or program supply.

• Fed-batch feeding of CHO K1, CHO-S, CHO-GS, and CHO DG44 cultures in serum-free development workflows.
• Evaluation of animal-origin-free feed strategies during clone screening, media/feed pairing, and nutrient supplementation studies.
• Small-scale shake flask, tube, and bench-scale bioreactor studies conducted at 37 °C and 5–10% CO2.
• Process characterization for recombinant protein, vaccine antigen, and biopharmaceutical manufacturing research where defined raw material sourcing is required.
• Comparability studies where osmolality, sterility, endotoxin specification, and documented shelf life are important procurement criteria.

Store CCM-SF-0036 at 2–8 °C protected from light. The product is shipped on blue ice to support cold-chain transit and should be transferred to refrigerated storage upon receipt. Do not use the material beyond the stated 12-month shelf life, and avoid repeated warming cycles or unnecessary light exposure. Handle aseptically in a qualified biosafety cabinet or controlled processing area. As with any concentrated feed, confirm addition timing, feed ratio, and dilution impact during process-specific optimization before routine use.
