Dulbecco’s MEM (DMEM) F-12 w/o Choline Chloride, Phenol Red

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 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.

Appearance
White to off-white, homogenous, free flowing powder
Solubility
Colorless to light yellow, clear, complete
pH
As Reported
Endotoxin
≤1EU/ml
Directions per Liter
Dissolve 11.98g 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.
