[Asia Economy Reporter Cho Hyun-ui] Samsung Biologics officially announced its self-developed cell line ‘S-Choice’ on the 5th. A cell line is a cell that proliferates massively outside the body to produce desired antibody drugs.
S-Choice is characterized by rapid proliferation and long-term survival compared to other cell lines. The cell expression amount is over 7 grams per liter titer (quantified antibody amount in the culture medium) immediately after cell line development, which is about twice the industry average (approximately 3-4 grams per liter at the time of commercial production).
The cell survival rate is over 90% until 21 days of serum culture, which is higher than the industry average (14 days). A Samsung Biologics official explained, "The higher the cell survival rate, the better we can select high-quality cell lines for mass production, which in turn increases productivity."
Another strength is the cell division speed of 18-20 hours, faster than major competitors’ cell lines (a full day, 24 hours). When culturing S-Choice with ‘Beacon,’ the latest cell incubator recently introduced by Samsung Biologics, the time required for cell line development is shortened from the industry average of 4 months to 3 months.
Kim Tae-han, CEO of Samsung Biologics, said, “Through S-Choice, we can provide services with overwhelming speed and quality compared to the existing global biopharmaceutical industry,” adding, “We expect that the powerful performance of S-Choice will enhance customer satisfaction, meet global pharmaceutical supply demands, and contribute to increasing the success rate of new drug development.”
