FGF-21 is a secreted growth factor of the FGF family, classified as an FGF-19 subfamily member. Proteins of the FGF family are known to play a central role with respect to both prenatal and postnatal growth and development, and regeneration of a variety of tissues by promoting cellular proliferation and differentiation. In the presence of beta Klotho (protein cofactor), FGF-21 signals via the FGFR receptors to stimulate insulin independent glucose uptake by adipocytes.
Aliases- FGF-21
- Recombinant Human Fibroblast Growth Factor 21 (FGF21)
Formulation- Lyophilized from 0.2 µm filtered solution in Tris and NaCl (pH 8.0)
Endotoxin Level- <1.0 EU/µg of recombinant protein as determined by the LAL method.
Storage Condition- The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2°- 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
