Human FGF-21

Human FGF-21

FGF-21 stands for fibroblast growth factor 21. Human FGF-21 is a recombinant protein optimized for use in cell culture, differentiation studies, and functional assays.


Human FGF-21 can be used for a variety of applications including:
  • In vitro investigation of glucose and lipid metabolism and endocrine signals.
  • In vivo studies of the biological effects on several tissues in murine models, e.g., of insulin resistance.

Background information

Fibroblast growth factor 21 (FGF-21) is a member of the FGF family, which controls several physiological and pathological development processes, including cell growth, cell survival, and morphogenesis. FGF-21 is expressed primarily in the liver and brown adipose tissue, and is involved in the control of fat metabolism, such as activation of glucose uptake by adipocytes. In the presence of the cofactor Beta-Klotho, FGF-21 binds both receptors FGFR1c and FGFR4. Altered levels of FGF-21 in patients suffering from type 2 diabetes, liver diseases, and obesity indicate a role of this protein in the pathogenesis of several metabolic diseases. Recombinant human FGF-21 shares 81% sequence identity with mouse FGF-21 and is known to be active on mouse cells.

Quality description

cytokines are suitable for a wide variety of cell culture applications. They are sterile-filtered prior to lyophilization. Generally, endotoxin levels are <0.1 ng/μg (<1 EU/μg), and purities are >95%. The biological activity is tested in appropriate bioassays.
