Frequently asked questions
01Which cell lines is this C-Cell grade validated on?
Used on CHO, Sf9 in manufacturer data and research reports. Ultrafiltered yeast hydrolysate for mammalian and insect cell culture. For other cell lines, start with a sample trial.
02What dose, and how is it added to the medium?
It varies with the cell type and culture mode: published studies used 0.5 g per litre for adherent Vero and 5 g per litre for suspension HEK293. Prepare a 30 g per litre stock directly in culture medium, filter through 0.2 µm and dilute in; trial three levels between 0.25 and 5 g per litre and read cell density and product.
03How should it be stored, and what is the shelf life?
Store at 10–30 °C in sealed, dry, clean conditions. Hygroscopic: keep the container tightly closed when not in use.
04How do I request a bulk quotation, and can you provide a COA?
Yes. This product is available in 500 g, 5 kg, 25 kg. Tell us your application and volume when requesting a quotation; we reply within one working day and can supply the COA, specification sheet, and technical data sheet.
