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:
WithWithout
• L-glutamine• HEPES
• Phenol Red


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, RPMI 1640 Medium requires 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.

Frequently asked questions (FAQs)

Do you have suggestions for improving viability when transfecting HL-60 cells with the Neon system?

Our online protocol suggests to use 50,000 cells with the 10 microliter tip. However, HL-60 cells do not survive well when transfected at low density. To improve viability you can try using at least 100,000 (better: 200,000) cells with the 10 microliter tips. Also, make sure your plasmid DNA is highly purified, as HL-60 cells are sensitive to LPS. If you observe that viability is good after 24 hours but decreases over the next 72 hours, you may either be using the wrong culture medium (RPMI 1640 + 10% FBS is recommended, do not use DMEM) or your batch of FBS contains low levels of cytotoxic contaminants.

Other possibilities are mycoplasma contamination or very high passage number of your cells. If this is the case please buy a fresh vial of HL-60 cells from ATCC and try your transfections again.

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.

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.
