This product is a serum-free medium for PER.C6 cells, a specialized formulation developed based on the concept of chemically defined (CD) media. It is specifically designed to support high-density suspension culture of human retinal embryonic cells (PER.C6) and efficient adenovirus vector production. Its core components precisely match the unique rapid growth and high-level viral packaging characteristics of this cell line. By enhancing key energy metabolism substrates, optimizing essential precursors for vector assembly, and incorporating cell protective components, it significantly improves cell proliferation stability, adenovirus vector yield, and batch-to-batch consistency while completely eliminating serum batch variability and animal-derived risks.
