FGF21 recombinant protein

FGF21

Cat. Num. AAA517007

• Applications: Cell Assay
• Synonyms: FGF21; FGF-21; Recombinant Human Fibroblast Growth Factor 21 (FGF21).; FGF21 recombinant protein

• Host: E Coli
• Form/Format: Lyophilized from 0.2 um filtered solution in Tris and NaCl (pH8.0)

• Applicable Applications for FGF21 recombinant protein: Cell Assay
• Species: Human
• Endotoxin Level: <1.0EU/ug of recombinant protein as determined by the LAL method.
• Sample Cell Assay Data: The bioactivity was determined in a NIH/3T3 cell proliferation assay with an ED50 <1ng/ml.
• Reconstitution: A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1mg/ml. This solution can then be diluted into other buffers.
• Preparation and Storage: The lyophilized protein is stable for at least one year from date of receipt at -70 degree C. Upon reconstitution, this cytokine can be stored in working aliquots at 2 degree -8 degree C for one month, or at -20 degree C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.

Related Product Information for FGF21 recombinant protein

Recombinant Human FGF21 was expressed in E Coli cells. The protein accession number is Q9NSA1
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.

NCBI Description

The protein encoded by this gene is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities and are involved in a variety of biological processes including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. The function of this growth factor has not yet been determined. [provided by RefSeq, Jul 2008]

Uniprot Description

FGF21: Stimulates glucose uptake in differentiated adipocytes via the induction of glucose transporter SLC2A1/GLUT1 expression (but not SLC2A4/GLUT4 expression). Activity requires the presence of KLB. Belongs to the heparin-binding growth factors family.
