RPMI-1640 Medium is used for the following applications:
  • Used in cell culture medium: Murine thymoma EL-4 cells were cultured in RPMI 1640 medium supplemented with other components
  • Used for the mycobacterial infection of splenocytes (in antibiotic-free RPMI 1640 medium)
  • Used for cell isolation and culture
  • Used in culture medium (as one of the component) during lymphocyte separation and culture, ELISPOT Assay, Ex Vivo Proliferation Assay
  • Used in medium for gp39 gene expression and CD40-Immunoglobuin binding assays
  • Used for the preparation of antifungal agents
RPMI 1640 Medium was developed at Roswell Park Memorial Institute in 1966 by Moore and his co-workers. A modification of McCoy′s 5A Medium, it was formulated to support lymphoblastoid cells in suspension culture, but it has since been shown to support a wide variety of cells that are anchorage dependent. Originally intended to be used with a serum supplement, RPMI 1640 has been shown to support several cell lines in the absence of serum. It has also been widely used in fusion protocols and in the growth of hybrid cells.

Biochem/physiol Actions

A non-steroidal anti-inflammatory drug that, when coadministered with morphine, potentiates its antinociceptive action and delays the development of tolerance. Dipyrone is a relatively selective inhibitor of cyclooxygenase-3 (COX-3), with lower activity against COX-1 and no activity against COX-2. Blocks PGE2-induced hyperalgesia in several models.


Formulated to contain 10.4 grams of powder per liter of medium.


Supplement with 2.0 g/L sodium bicarbonate.

Other Notes

Phenol red has been shown to interfere with the growth of some cells at clonal densities. Use this medium when working with stem cells or when growing cells at low densities. Also recommended for in vitro diagnostics use.

The ELISpot Assay Enables Functional Analysis of Cellular Immunology

The enzyme-linked immunosorbent spot (ELISpot ) assay enables visualization of multiple secretory products from a single responding cell. The ELISpot provides both qualitative (type of immune protein) and quantitative (number of responding cells) information.
