Frequently asked questions
01Which cell lines is this C-Cell grade validated on?
Used on CHO, HEK293, Sf9 in manufacturer data and research reports. Ultrafiltered yeast hydrolysate for mammalian and insect cell proliferation and protein expression. 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. 3 years
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.
