L-Aspartic, L-Glutamic Acid, Glycine, L-Proline and L-Serine 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. The medium is for research use only and not approved for human or animal
use or for application in any in vitro diagnostic procedure. Storage of the medium and
supplements Please note that the basal medium has to be stored at 4°C up to 8°C but
never should be frozen. The supplement has to be stored at -20°C. Protect from light for
a longer time period.
Preparing and Stability:
Thaw the supplement mixture at 37°C before adding to the basal medium. After thawing
please rinse the bottle and the tube with 70% ethanol as protection. Remove ethanol
excess before opening the cap of the tube. After adding the supplement mixture to the
basal medium slew carefully to get a homogenous medium. Please be careful not to touch
the tube or bottle interior threads with your fingers. Please avoid long term exposure to
light because some components are light sensitive. Also do not warm up the medium over
37°C. All this protects your medium against contamination or degradation of essential
components.
