Using RPMI
RPMI 1640 Medium is unique from other media because it contains the reducing agent glutathione and high concentrations of vitamins. RPMI 1640 Medium contains biotin, vitamin B₁₂, and PABA, which are not found in Eagle’s Minimal Essential Medium or Dulbecco’s Modified Eagle Medium. In addition, the vitamins inositol and choline are present in very high concentrations. RPMI 1640 Medium contains no proteins, lipids, or growth factors; therefore, requiring supplementation, commonly with 10% Fetal Bovine Serum (FBS). RPMI 1640 Medium uses a sodium bicarbonate buffer system (2.0 g/L), and therefore requires a 5–10% CO₂environment to maintain physiological pH. Powder forms of Gibco® cell culture media require sodium bicarbonate supplementation, pH adjustment, and filtration at the time of preparation (see protocol for details).
