Gibco™ RPMI 1640 Medium (ATCC modification)

RPMI 1640 Medium was originally developed to culture human leukemic cells in suspension and as a monolayer. Roswell Park Memorial Institute (RPMI) 1640 Medium has since been found suitable for a variety of mammalian cells, including HeLa, Jurkat, MCF-7, PC12, PBMC, astrocytes, and carcinomas. We offer a variety of RPMI 1640 Medium modifications for a range of cell culture applications. Find the right formulation using the media selector tool.

This RPMI is modified as follows:

With: L-glutamine, HEPES, Phenol Red, Sodium Pyruvate, High glucose, Low sodium bicarbonate

The complete formulation is available.

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. This RPMI formulation has been modified by ATCC to contain high glucose, low sodium bicarbonate, sodium pyruvate, HEPES, and low L-glutamine. RPMI 1640 Medium contains no proteins, lipids, or growth factors. Therefore, RPMI 1640 Medium requires supplementation, commonly with 10% Fetal Bovine Serum (FBS). RPMI 1640 Medium uses a sodium bicarbonate buffer system (1.5 g/L) and therefore requires a 5–7% CO₂ environment to maintain physiological pH.
