CHO Transient Expression Supplement, ADCF

CCM-SF-0033 is a concentrated CHO transient expression supplement for serum-free, animal-derived component-free workflows. It is intended for use with suspension CHO expression systems, including CHO-S-type cultures and comparable high-density transient production platforms. The product is supplied as a liquid 25–100X supplement set in a 500 mL + 50 mL pack, enabling process teams to tune addition rates during small-scale screening, shake-flask development, and stirred-vessel transfer studies.

The formulation is positioned for recombinant protein, antibody, antigen, and other biopharma research production campaigns where chemically defined or animal origin-free inputs are preferred. Recommended culture conditions from the product specification are 37 °C and 5–10% CO2. The stated endotoxin specification is ≤20 EU/mL, and the shelf life is 12 months when stored as directed. For related defined and serum-free products, buyers can review the serum-free media category or request matching support for complete CHO expression media systems.

• Transient expression of recombinant proteins in suspension CHO culture during R&D, feasibility, and pre-scale production runs.
• Supplementation of serum-free CHO workflows where animal-derived component-free inputs are specified by process development or quality teams.
• Expression-condition screening for feed timing, supplement ratio, viable cell density, productivity, and culture-duration studies.
• Support for CHO-S-type and other suspension CHO platforms operated at 37 °C under 5–10% CO2.
• Production of research-grade antibodies, proteins, antigens, and other biologics-related materials for analytical characterization and process comparison.
• Procurement standardization for teams that require a documented liquid supplement with a defined concentration range, endotoxin limit, shelf life, and cold-chain shipping conditions.

Store CCM-SF-0033 at 2–8 °C protected from light. Do not store near uncontrolled heat sources or in locations subject to repeated temperature cycling. The product ships on blue ice to maintain refrigerated transit conditions, and receiving teams should inspect the package on arrival, record condition and date received, and return the supplement to 2–8 °C storage promptly. Use aseptic technique when opening and dispensing. Mix gently before use if permitted by the local process instruction, and avoid unnecessary foaming during transfer. The stated shelf life is 12 months when unopened and stored under the specified conditions.
