FGF21 is a secreted growth factor of the FGF family, classified as an FGF19 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), FGF21 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° to +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.
