【Product Description】

Medium 199 was the first nutritionally defined medium developed by Morgan, Morton, and Parker in 1950.This complex medium was formulated specifically for nutritional studies on primary chick embryo fibroblasts in the absence of any additives. It was observed that explanted tissue could survive in Medium 199 without serum but long term cultivation of cells required supplementation of the medium with serum.

Medium 199 is formulated with either Hank's salts or Earle's salts. The medium when supplemented with serum can be used for growth of a wide variety of cells. Medium 199 is presently used for the maintenance of non-transformed cells, vaccine and virus production and primary explants of epithelial cells.

Users are advised to review the literature for recommendations regarding medium supplementation and physiological growth requirements specific for different cell lines.
