• Host: E Coli
• Purity/Purification: >95% by SDS-PAGE and HPLC analyses.
• Form/Format: Lyophilized from a 0.2mm filtered concentrated solution in PBS, pH 7.4.
• Sequence: MHPIPDSSPL LQFGGQVRQR YLYTDDAQQT EAHLEIREDG TVGGAADQSP ESLLQLKALK PGVIQILGVK TSRFLCQRPD GALYGSLHFD PEACSFRELL LEDGYNVYQS EAHGLPLHLP GNKSPHRDPA PRGPARFLPL PGLPPALPEP PGILAPQPPD VGSSDPLSMV GPSQGRSPSY AS
• Sequence Length: 209

• Molecular Weight Information: Approximately 19.1 kDa, a single non-glycosylated polypeptide chain containing 179 amino acids.
• Biological Activity: Fully biologically active when compared to standard. The ED50 as determined by the dose-dependent stimulation of the proliferation of BaF3 cells expressing FGF receptors is 0.06-0.4ug/ml in the presence of betaKlotho and Heparin.
• Endotoxin Level: Less than 1EU/mg of rHuFGF-21 as determined by LAL method.
• Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/ml. Stock solutions should be apportioned into working aliquots and stored at <-20 degree C. Further dilutions should be made in appropriate buffered solutions.
• Preparation and Storage: This lyophilized preparation is stable for several weeks at 2-8 degree C, but should be kept at -20 degree C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 degree C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 degree C to -70 degree C. Avoid repeated freeze/thaw cycles.

Related Product Information for FGF21 active protein

Fibroblast growth factor 21 (FGF21) belongs to the large FGF family which has at least 23 members. All FGF family members are heparin binding growth factors with a core 120 amino acid (aa) FGF domain that allows for a common tertiary structure. FGFs are expressed during embryonic development and in restricted adult tissues. Four distinct but related classes of FGF receptors, FGF R1, 2, 3, and 4, exist. FGF-21, in the presence of betaKlotho as a protein cofactor, signals through the FGFR 1c and 4 receptors and stimulates 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.
