Fetalgro® Bovine Growth Serum (BGS)
Fetalgro® is our proprietary bovine growth serum (BGS) supplemented with additives that match or outperform FBS' cell growth capabilities in many cell lines including CHO and Vero.

- Fetalgro® is our proprietary blend of serum, supplemented with additives including our flagship product Lipogro®.
- Fetalgro® is proven to match and in many cases outperform FBS in numerous cell lines including U2OS, HEK293, CHO, Vero, NB, HeLa, A549 and MDBK.
- Fetalgro® is a fraction of the price of FBS due to the low cost of its base material.
- Fetalgro® has a much more reliable supply line than FBS, ensuring constant availability.
