RPMI 1640 (1X Solution) Without L-Glutamine and L-Leucine
RPMI 1640 was originally developed by Moore and his colleagues at Roswell Park Memorial Institute (RPMI). It was based on the RPMI 1630 line of media which utilized a bicarbonate buffering system and alterations in the amounts of amino acids and vitamins. A Dutch Modification of RPMI 1640 is also available through MP. The Dutch Modification contains 6400 mg/L sodium chloride instead of 6000 mg/L, 1000 mg/L sodium bicarbonate instead of 2000 mg/L, and 20 mM HEPES.
Williams Medium E, Powder, With L-Glutamine, Without Sodium Bicarbonate
Isolated epithelial cells, as described in his sequential plating method by Williams, et al., in 1971, were originally cultivated in a rich medium known as Williams' Medium D. From these early newborn animal studies, Williams and Gunn developed a subsequent medium, Williams' Medium E, for the long-term cultivation of adult rat liver epithelial cells.
