CHOlean | Medium Sample

CHOlean Medium is a complete chemically defined, animal-component–free, protein-free, and ready-to-use cell culture medium. It has a lean medium formulation designed for batch and fed-batch processes with different CHO cell lines. CHOlean is developed with a minimal set of well-balanced components to achieve a lean, robust and flexible medium basis. In addition, it is capable of competing with state-of-the-art media for highest cell growth and product titer. The formulation is suitable for a broad range of different CHO cell lines, including K1 and DG44. Furthermore, CHOlean is optimized for easy adaptation from other media and is a robust platform to build high-performance fed-batch processes on. The medium supports cell growth and production of recombinant proteins and antibodies in suspension culture. It can be used in research or in manufacturing applications.

• For CHO cell lines
• Chemically defined, serum-free, animal component-free and hydrolysate-free
• Little or no adaptation required from other serum-free media
• Supports stable growth of suspension cells at high viability in seed train culture
• w/o L-glutamine
• w/o HT (hypoxanthine/thymidine)
• Appoved by ISO 9001 QMS
