.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 5–10% CO2
environment to maintain physiological pH.cGMP manufacturing and quality system
