Product Feed Media
세포배양배지
아지노모도㈜의 아미노산 기술과 30년이상 동물세포배양배지사업에 대한 경험을 바탕으로 개발된 동물세포배양배지입니다. 최근엔 모두 Chemically Defined 성분으로 동물유래성분을 포함하지 않은 고성능 배지를 제조·판매하고 있습니다.
CHO 세포주의 배양 성능을 향상시킬 수 있도록 설계된 고농축 Feed 배지입니다. CELLiST™ FEED Media는 단백질 품질과 기능을 유지하면서 목표하는 세포 성장과 생산성을 달성할 수 있도록 지원합니다. FEED2는 모든 배지와 함께 사용할 수 있지만, 기본적으로는 CELLiST™ BASAL Media와 함께 사용하는데 최적화되었습니다.
CELLiST™ F7 feed medium employs Ajinomoto Group’s proprietary cysteine-stabilization technology, ensuring high concentrations of cysteine are continuously available for your CHO cells throughout the culture, leading to greatly improved performance. This is achieved by drastically reducing the naturally-occurring oxidation of L-cysteine to cystine dimers, leading to increase in the amounts of available cysteine, while also improving stability and shelf-life.

Optimization of amino acids formulation through joint development
with A*STAR’s Bioprocess Technology Institute.
Cutting-edge ‘Digital Twin’ and AI technologies were employed for optimizing metabolic flux in key pathways, such as the TCA cycle,
leading to significant improvement in specific productivity and culture growth, and reduced levels of toxic by-products.
Key Findings on CHO Cell Metabolism and Feed Media :
Our study reveals that feed media enriched with asparagine and aspartate significantly enhance CHO cell growth and IgG1 productivity compared to glutamate-based feeds. We discovered that a balanced Asn/Asp ratio of around 3 optimizes energy metabolism, reduces ammonia accumulation, and supports efficient TCA cycle flux. These insights contribute to improved bioprocessing strategies for higher cell density and antibody production.
