C-Cell 세포배양 등급 단백질 가수분해물

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.

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.

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.

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.

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.

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.

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.
