CDM-HD Chemically Defined Medium (Powder)

FiberCell’s CDM-HD Chemically Defined Medium is an additive for basal DMEM media that enables long-term high density culture with protein-free chemically defined media. It avoids the hidden costs associated with serum use when producing mAbs, for example, and has been shown to be ideal for exosome production applications in a variety of different cell lines (publications below).

CDM-HD is protein free and designed specifically for the FiberCell hollow fibre bioreactor although it has also been shown to work very well in high density 2-compartment flasks. Download the FiberCell CDM-HD brochure.

Chemically define medium for use in high density bioreactors

  • Supplied as an easy to store powder
  • Avoids the typical risks of using serum (viruses, prions and mycoplasma)
  • No proteins, No animal-derived components, No detergents
  • Single step adaptation for most cell lines and hybridomas
  • Highly consistent lot-to-lot, stable at 4°C for 1 month once made up
  • Gives highest bioreactor yields

Easier purification

CDM-HD chemically defined medium is a protein and surfactant-free substitute designed specifically for high density cell culture in the FiberCell® hollow fibre bioreactor. Using CDM-HD means simplified purification protocols and increased net yield.

How is it used?

CDM-HD is provided as a pack of dry powder to be made up to 1 litre and sterile-filtered to be used just like serum –  at a concentration of 10% in DMEM/High, for example. DMEM is the preferred basal media for highest cell density. One pack containing 33.36g enables 10 litres of serum-free media to be produced at low cost.

Optimized for high cell density bioreactors

CDM-HD chemically defined medium is fully optimized to exploit the unique high density conditions in a hollow fibre bioreactor or in high density culture flasks. (Not for standard flasks or rollers). An adaptation period is not needed, you can replace serum with DMEM/10%CDM-HD once cells are growing at high density. CDM-HD contains no detergents or other cell membrane stabilizing agents that sometimes interfere with assays or precipitations [see composition table].
