Using Opti-MEM I Medium：
Opti-MEM I Reduced-Serum Medium is a unique medium that contains insulin, transferrin, hypoxanthine, thymidine, and trace elements. These additional components allow for a reduction in serum supplementation by at least 50%. Opti-MEM I medium uses a sodium bicarbonate buffer system (2.4 g/L), and therefore requires a 510% CO2 environment to maintain physiological pH.
