RPMI 1640

RPMI 1640, also known as RPMI medium, is a growth medium used in cell culture.^[1] RPMI 1640 was developed by George E. Moore, Robert E. Gerner, and H. Addison Franklin in 1966 at Roswell Park Memorial Institute, from where it derives its name.^[2] A modification of McCoy′s 5A medium (or RPMI 1630), it was originally formulated to support lymphoblastoid cells in suspension cultures, but can also support a wide variety of adherent cells.

It has traditionally been used for growth of human lymphocytes. This medium contains a great deal of phosphate and is formulated for use in a 5% carbon dioxide atmosphere. RPMI 1640 has traditionally been used for the serum-free expansion of human lymphoid cells. RPMI 1640 uses a bicarbonate buffering system and differs from most mammalian cell culture media in its typical pH 8 formulation. Properly supplemented with serum or an adequate serum replacement, RPMI 1640 allows the cultivation of many cell types, especially human T/B-lymphocytes, bone marrow cells, and hybridoma cells.

Composition

One liter of RPMI 1640 contains:^[2]

Glucose (2 g)
pH indicator (phenol red, 5 mg)
Salts (6 g sodium chloride, 2 g sodium bicarbonate, 1.512 g disodium phosphate, 400 mg potassium chloride, 100 mg magnesium sulfate, and 100 mg calcium nitrate)
Amino acids (300 mg glutamine; 200 mg arginine; 50 mg each asparagine, cystine, leucine, and isoleucine; 40 mg lysine hydrochloride; 30 mg serine; 20 mg each aspartic acid, glutamic acid, hydroxyproline, proline, threonine, tyrosine, and valine; 15 mg each histidine, methionine, and phenylalanine; 10 mg glycine; 5 mg tryptophan; and 1 mg reduced glutathione)
Vitamins (35 mg i-inositol; 3 mg choline chloride; 1 mg each para-aminobenzoic acid, folic acid, nicotinamide, pyridoxine hydrochloride, and thiamine hydrochloride; 0.25 mg calcium pantothenate; 0.2 mg each biotin and riboflavin; and 0.005 mg cyanocobalamin)
