Most products require no additional agreements. Cell lines and certain biological materials require a Material Transfer Agreement (MTA) on first purchase from each supplier. We handle this digitally - both parties sign online before shipment. Subsequent orders from the same supplier proceed immediately.
Defined Bioscience’s FGF2 Screening Kit provides a complete set of recombinant fibroblast growth factor 2 (FGF2) variants for comparative evaluation in cultivated-meat and cellular-agriculture workflows. The kit enables rapid assessment of thermostable and species-specific homologs to identify the optimal growth factor for cell proliferation, differentiation, and maintenance.
Each kit includes four purified, animal-origin-free proteins produced in E. coli with >95 % purity: FGF2-G3 (Human), FGF2-G3 (Bovine/Porcine), FGF2 (Chicken), and FGF2 (Tuna). The G3 variants incorporate nine stabilising mutations that extend half-life and reduce the need for frequent supplementation, while the native chicken and tuna forms allow for targeted testing with avian and aquatic cell types. All variants are supplied at 1 mg/mL in defined storage buffers and validated through NIH-3T3 proliferation assays (EC₅₀ < 1–2 ng/mL).
Available in 10 µg or 50 µg aliquots, the FGF2 Screening Kit supports process development and media optimisation in serum-free and defined systems. It allows cultivated-meat researchers to empirically determine which FGF2 homolog delivers the best performance for their specific cell line, reducing trial time and cost during media design.
For research and development use only. Not for human or diagnostic applications.

Cellag Bio is the structured intelligence layer for cultivated meat R&D — scattered published research distilled into decision-ready records: what worked, what failed, the likely cause, and what to do instead. Before committing budget to a medium, reagent, or cell line, check the evidence behind it: real experimental outcomes and failure modes, not marketing claims.
Search by media, reagent, cell line or species (e.g. "Beefy-9" or "B8") to find the records that use it.
