Ham's Nutrient Mixtures were originally developed to support growth of several clones of Chinese hamster ovary (CHO) cells, as well as clones of HeLa and mouse L-cells. Both mixtures were formulated for use with or without serum supplementation, depending on the cell type being cultured.

Ham's F-10 has been shown to support the growth of human diploid cells, white blood cells for chromosomal analysis, primary explants of rat, rabbit and chicken tissues.

Ham's F-12 has been used for the growth of primary rat hepatocytes and rat prostate epithelial cells. A clonal toxicity assay using CHO cells has also been reported with Ham's F-12 as the medium of choice. Ham's F-12 is also available with 25 mM HEPES buffer that provides more effective buffering in the optimum pH range of 7.2-7.4.

Coon's modification of Ham's F-12 was developed for culturing hybrid cells that were produced by viral fusion. The modification consists of doubling the amino acids and pyruvate and including ascorbic acid. The salt concentrations have also been altered. The formula contains 0.863 mg/L zinc sulfate, which may render it unsuitable for culturing mouse L-cells.

Kaighn's modification of Ham's F-12 and Coon's F-12 has increased concentrations of amino acids and pyruvate, as well as modified salts (Konigsbergs). This medium was designed to support the growth of differentiated rat and chicken cells, and primary human liver cells.
