Serum-Free and Animal-Free Cell Culture
The elimination of serum and animal components in culture media is an important step towards a defined cell culture process. Defined media contain only products and materials with known chemical identity such as small molecules, salts, and fatty acids. These media may also include recombinant proteins that are not produced in animal systems.
Incorporating serum-free or animal-free media will benefit your cell culture process in several ways:
- Improving consistency by reducing variability in media composition
- Simplifying compliance with regulatory guidelines
- Simplifying comparability testing if raw material changes are required
- Reducing time-to-market for your cell product
If you’re not ready for serum-free or animal-free culture, visit our Cell Culture Reagents page for classical media, serum products, and basement membrane extracts.
Serum-Free Cell Culture
Serum-free cell culture media will improve your experimental consistency by reducing the number of unidentified culture components as well as the effects of unknown levels of vitamins, hormones, and growth factors. In addition, serum-free media
- Reduce the risk of potential viral contaminants that may be present in the serum
- Reduce the cost and inconvenience of batch testing sera
- Eliminate uncertainty about global supply fluctuations
- Simplify purification and downstream processing
These media components do not require supplementation with fetal bovine serum (fetal calf serum; FBS) to support cell survival, proliferation, or function:
- N-2 MAX and N21-MAX supplements for NPC derivation, maintenance, and differentiation
- StemXVivo™ Serum-Free Human MSC Expansion Media and Freezing Media

Animal-Free Cell Culture
Animal-free media and their components are never exposed to potential contamination by animal products at any point during their manufacturing. In addition to its importance for robust culture processes, adopting animal-free materials also reduces the use of animals in reagent production. These materials support translational research by
- Eliminating risk of contamination with mammalian pathogens
- Reducing manufacturing risk by reducing batch failure
- Eliminating variability due to trace animal components
- GMP N-2 MAX Media Supplement, animal-free
- GMP and Ancillary Material grade small molecules, animal-free

Cell culture requires understanding the nutrient and growth factor requirements of the cell population under study. This knowledge is valuable for the optimization of base media formulation and supplements including growth factors, cytokines, hormones, small molecules, and amino acids. Serum, such as fetal bovine serum (FBS), can supply unidentified factors which may be required for cell growth. The use of chemically defined media minimizes exposure of cultured cells to unidentified factors. Certified xeno-free, animal-free, or GMP grades of cell culture media are important for applications such as cell and gene therapy which involve human patient treatment. Well optimized cell culture media maintain the desired cell phenotype, robust proliferation, and high viability.
