This product is a serum-free medium for SOgE cells, featuring a specialized formulation developed based on the concept of chemically defined (CD) culture. It is designed to support high-density cultivation and efficient production applications for specific SOgE cell lines. Its core formulation precisely optimizes energy metabolism pathways and key nutritional components to effectively maintain high-viability cell growth and promote target product expression, while completely eliminating batch-to-batch variability and biosafety risks associated with serum introduction.
