Why should I use serum-free/chemically-defined media?


Serum-free and chemically-defined media allow for a more consistent culture system (reducing lot-to-lot variation) because they do not contain undefined components that may be introduced by the addition of serum. Serum-free media are lower in protein content than medium supplemented with serum, which can simplify the purification process and increase the yield of the end-product. In addition, the end-user also does not need to take time to qualify and secure lots of FBS for activity.
