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	Without
• L-glutamine	• HEPES
• Phenol Red	• Sodium Bicarbonate

The complete formulation is available.

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% CO₂ environment 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).

よくあるご質問（FAQ）

How light sensitive is RPMI 1640 media? Should I also be protecting it from LED light?

While we know that different wavelengths of light are worse than others for exposure, we would recommend as a best practice to protect the medium from all forms of light exposure including LEDs, as much as possible to ensure optimal performance, as several components within the medium are light sensitive, such as vitamins.

What is the density (g/L) for RPMI 1640 Medium?

We have specific gravity information for RPMI 1640 Medium: 1.006 kg/L. In this case, the specific gravity is the same as density as the solvent is water.

What is the shelf life of my powdered media once I reconstitute it?

Expiration date of most Gibco reconstituted dry format media (AGT or DPM) has not been established; end users should assess performance and stability of this reconstituted media in a system that is relevant to their process. A dry format product (either DPM or AGT) will age upon storage and while we may not be able to detect which component(s) degrade since we can't measure every component, that doesn't mean that the reconstituted liquid will have the same stability as a fresh liquid made by direct weigh methods.

How long can I keep my media after supplementing with serum?

Generally speaking, media can be used for up to three weeks after supplementation with serum. There are no formal studies to support this, but it is the rule of thumb used by our scientists.

My medium was shipped at room temperature but it is supposed to be stored refrigerated. Is it okay?

We routinely ship media that require long-term storage in the refrigerator at room temperature. We have done studies on representative media formulations to show that media can be at room temperature for up to a week without a problem.
