General description

Fibroblast Growth Factor 4 (FGF-4) is a growth factor predominantly expressed during embryonic development, playing a key role in limb development. In culture, FGF-4 has been shown to be an important growth factor for fibroblasts and endothelial cells. Human FGF-4 shares high homology and cross-reactivity with the mouse protein. Recombinant human FGF-4, produced in E.coli, is a non-glycosylated protein containing 177 amino acids and having a total molecular mass of 19 kDa.

Physical form

Lyophilized from a sterile solution containing 10 mM Sodium phosphate buffer and 75 mM NaCl. .


When reconstituting the product, gently pipet and wash down the sides of the vial to ensure full recovery of the protein into solution. It is recommended to reconstitute the lyophilized product with sterile water at a concentration of 0.1 mg/mL, which can be further diluted into other aqueous solutions.
