Description
CelliMax® CHO FGb Medium is a chemically defined (CD) feed medium (amino acids only) for CHO cells, chemically defined feed containing only amino acids. Combined with CelliMax® CHO FGa or FGa plus, it supports high-density growth of CHO cell lines and enhances protein expression. Manufactured by our partner CelluPro and supplied in the EU by SeamlessBio.
Key features
- Chemically defined, amino acids only
- Cell lines: CHO-K1, CHO-DG44, CHO-S, CHO-DXB11 and GS-knockout CHO lines
- Applications: fed-batch culture in combination with CelliMax® CHO FGa or FGa plus
- Powder format for in-house preparation at any scale
- No L-glutamine included – add L-glutamine or a stabilised dipeptide according to your cell line and process
