With our deep expertise and commitment to excellence, we help you reduce time to market and keep costs low, all while achieving the best possible outcomes for your journey.


High-performing CHO-K1-based cell line development platform
Samsung Biologics’ Cell Line Development service offers clients a cell line process that combines world-class technology, a strategic mindset, and a collaborative spirit to deliver maximized titers and enhanced cell viability.
S-CHOice® builds on glutamine synthase (GS) knock-out Chinese hamster ovary (CHO) cell line technology and shows improved titers reaching above 7 g/L for standard monoclonal antibodies. The cell line also shows enhanced viability with over 90% at day-21 in a fed-batch study.

Efficient screening of a large number of cells and increasing the chances of identifying high-yield/high-quality cell lines are essential for high throughput. While selecting the handful of cells that are most important can take 2-3 months of intensive and expensive manual manipulation. Enhanced by the innovative Beacon® platform, we develop high-yield/ high-quality cell lines within a shorter timeframe.
