C-Cell cell-culture-grade protein hydrolysates
Ultrafiltered, low-endotoxin plant and yeast protein hydrolysates made by Organotechnie, France, for serum-free and low-serum culture of CHO, HEK293, Vero, mesenchymal stromal and insect cells. STBIO MEDIA is the distributor in Taiwan, supplying samples, specifications and batch COAs.
Fetal bovine serum is expensive, variable between batches and carries animal-origin risk, so vaccine, monoclonal antibody, cell therapy and cultivated meat processes all look for ways to use less of it. Cell-culture-grade protein hydrolysates are the most common replacement supplement: plant or yeast protein is cut into peptides and amino acids, ultrafiltered to remove large molecules and controlled for endotoxin, so it can supply part of the nutrition and growth factors serum used to provide.
C-Cell is the range Organotechnie designed for cell culture, split by raw material into soy, pea, guar, broad bean, rice, wheat and yeast grades, each with validation data on CHO, HEK293 or Vero. STBIO MEDIA has distributed the range since 2023, holds stock in Taiwan and provides free samples.

Cell lines and applications
- CHOCHO cells: monoclonal antibodies and recombinant proteinsAdded to serum-free or low-serum basal media to supply peptides and growth factors, supporting cell density and product accumulation. Suspension cultures usually take a higher dose than adherent ones. Most C-Cell grades are validated primarily on CHO.S104S146BS186P112G115F120R116R123Y109Y121
- HEK293HEK293 transient expressionAn Organotechnie R&D report expressed IL-4 in HEK293-6E and compared plant-derived C-Cell grades with Tryptone N1; P112, G115 and S204 gave markedly higher expression than the control.S104S204P112G115W106Y109
- VeroVero cells and serum reduction for vaccine productionA study by Inserm and Organotechnie achieved the same Vero proliferation with 5% serum plus 0.5 g/L peptone as with 10% serum, halving serum use.W106
- MSCMesenchymal stromal cells and extracellular vesicle productionAn Inserm study coated culture surfaces with plant peptone and used EV-depleted fetal bovine serum to raise extracellular vesicle yield from umbilical cord MSCs while retaining function.
- Sf9Insect cells and baculovirus expressionYeast-derived Y109 and Y121 are suited to proliferation and protein expression in Sf9 and other insect cells.Y109Y121
Frequently asked questions
01What is C-Cell?
C-Cell is the cell-culture-grade protein hydrolysate range from Organotechnie S.A.S., France: plant or yeast proteins enzymatically hydrolysed and ultrafiltered, with low endotoxin, used to supply peptides and growth factors in serum-free or low-serum media. STBIO MEDIA is the distributor in Taiwan.
02How does C-Cell differ from an ordinary peptone?
Three things: ultrafiltration (removing large molecules and potential viral or endotoxin load), an endotoxin specification, and performance testing on cell lines. Ordinary fermentation peptones lack these and often inhibit growth or introduce endotoxin when added to cell culture media.
03What dose should I start with?
It varies widely with the cell type and culture mode. In published studies, adherent Vero cells used 0.5 g per litre (0.05%) while suspension HEK293 used 0.5% (5 g per litre), a tenfold difference. Trial three levels between 0.25 and 5 g per litre, starting low for adherent cells and high for suspension cells, then read cell density and product.
04Can it fully replace serum?
It depends on the cell line. Published data show serum can be cut from 10% to 5% in Vero and partially replaced in CHO; fully serum-free culture usually needs an optimised basal medium and adaptation. We supply samples so you can verify in your own system.
05What documentation is available?
Each batch comes with a COA (including endotoxin), a TDS and an SDS; the manufacturer can provide animal-origin, non-GMO and process statements. Contact us for documents required for regulatory filings.
06Is it animal-origin-free?
Plant- and yeast-derived C-Cell grades contain no animal-derived raw material; the origin of enzymes and processing aids is stated in the manufacturer's declaration, available with the sample.
07Minimum order and lead time?
Samples are free; order sizes follow the pack formats. Common grades are stocked in Taiwan and the rest ship from France. Tell us the cell line, application and volume via the quotation form.
