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 lymphoblastic 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. This medium is suitable for culturing human normal and neoplastic leukocytes.
Roswell Park Memorial Institute medium is commonly known as RPMI. It is a form of medium used in cell culture and tissue culture. This medium contains phosphate and is formulated for use in a 5% carbon dioxide atmosphere. It is used for the growth of human lymphoid cells.
Used in cell culture medium (i.e. Murine thymoma EL-4 cells were cultured in RPMI 1640 medium supplemented with other components)
