Dulbecco’s MEM is the most widely used modification of BME. It contains a 4-fold higher concentration of amino acids and vitamins. Non-essential amino acids and certain essential trace elements were added. The bicarbonate concentration was increased. The standard formula for DMEM is with 1000mg/ml glucose. DMEM “High Glucose“ with 4500mg/ml aides in the cultivation of certain cell types. DMEM was originally developed for the culture of mice embryonic cells. Today, it finds a broad application of serum free culture of normal and transformed mouse and chicken cells.

Ham's Nutrient Mixtures were originally developed to support growth of several clones of Chinese hamster ovary (CHO) cells, of HeLa and of mouse L-cells. Ham’s mixtures were formulated for use with or without serum supplementation, depending on the cell type being cultured. Ham’s F-12 was developed for growth of primary rat hepatocytes and rat prostate epithelial cells. It is also used in a clonal toxicity assay using CHO cells.

Directions per Liter
Dissolve 14.28g in 800-900ml of ddH2O, stirring gently until completely solubilized. If required, add 1.2g sodium bicarbonate with stirring. Adjust pH of the medium to 0.1-0.3 pH unit below the desired level. Add additional water to bring the solution to 1L. Filter-sterilize using a 0.22 micron membrane filter. Aliquot into sterile containers. Do not autoclave. Contains heat-labile compounds that can be damaged with autoclaving.
Storage and Stability
Store powdered media at RT. Stable for 12 months after receipt. Opened bottles should be capped tightly and kept in a dark, low humidity environment. Prepared media should be kept at 4°C and used within a short period of time.
