4Cell CHO Media & Feed Portfolio

We will be exhibiting and presenting a luncheon seminar at BioJapan 2025, which will be held at Pacifico Yokohama from October 8 to 10, 2025. At our booth, we will introduce our cell line development services and media optimization services that achieve a scalable fed-batch process with a monoclonal antibody titer of up to 10 g/L in just 9 weeks, from DNA to RCB. We will also showcase single-use culture vessels for process development. In addition, during the luncheon seminar, we will provide a clear overview of Sartorius' CLD services, making it easy to understand for those who are new to the topic. If you are considering shortening timelines, optimizing product quality, or exploring flexible development strategies, please join us. We look forward to seeing you there. Event Overview: October 8 (Wed) - 10 (Fri), 2025, Pacifico Yokohama Exhibition Booth: Small Booth Number D-109 Luncheon Seminar: Title: Minimizing Risks in CHO Cell Line Development through Automation and Predictive Models Seminar Date and Time: October 9 (Thu) 11:30 AM - 12:30 PM

To maximize the performance of CHO cells, it is necessary to select the optimal medium for each clone and further optimize the process parameters. Sartorius offers a variety of basic media and feeds suitable for Fed-batch culture of major CHO cell lines such as CHO-DG44, K1, S, and GS. In this webinar, we will introduce a case study that combines these CHO media, the automated microbioreactor Ambr15, and the experimental design software MODDE to conduct medium screening and process optimization in a short period. We will also provide information about our Benchmark Study service, which allows you to outsource the selection of the optimal medium and process development for your specific cell line to our research institute in Germany. 【Seminar Overview】 ▪ Date: March 6, 2025 (Thursday) from 3:00 PM (approximately 40 minutes) ▪ Method: Webinar recorded broadcast [Japanese, Free] If you are unable to participate on the day, please register first. We will send you a viewing URL later. *We kindly ask that participants from other companies in the same industry, as well as those using email addresses not affiliated with your organization, refrain from joining.
