Optimal cell growth – maximum expression
Our First CHOice® medium is a highly productive cell culture medium optimized for mammalian cells growing in suspension.
The components of First CHOice® are optimally balanced and facilitate excellent cell growth as well as high productivity in batch and fed-batch processes.
Our First CHOice® quality commitment:
- Chemically defined products
- No animal-derived components
The First CHOice® media platform has been developed in close cooperation with customers and partners using CHO‑S, CHO‑DG44 and CHO‑K1 cell lines. It minimizes formation of stress-induced metabolic products such as lactate and ammonium, and ensures high product quality and cell viability.
The First CHOice® Medium, the First CHOice® Feed Alpha and First CHOice® Feed Beta are available in powder form and as ready-to-use liquids.
