| Primary Accession | Q9JJN1 |
|---|---|
| Species | Mouse |
| Sequence | Ala29-Ser210 |
| Purity | > 97% as analyzed by SDS-PAGE > 97% as analyzed by HPLC |
| Endotoxin Level | < 1 EU/ µg of protein by LAL method |
| Biological Activity | Fully biologically active when compared to standard. The ED50 as determined by thymidine uptake assay using FGF-receptors transfected BaF3 cells is less than 0.5 µg/ml, corresponding to a specific activity of > 2.0 × 103 IU/mg in the presence of 5.0 µg/ml of rMuKlotho-β and 10.0 µg/ml of heparin. |
| Expression System | E. coli |
| Theoretical Molecular Weight | 19.9 kDa |
| Formulation | Lyophilized from a 0.2 µm filtered solution in 3 × PBS, pH 7.4. |
| Reconstitution | It is recommended that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute the lyophilized powder in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/ml. |
| Storage & Stability | Upon receiving, this product remains stable for up to 6 months at -70°C or -20°C. Upon reconstitution, the product should be stable for up to 1 week at 4°C or up to 3 months at -20°C. Avoid repeated freeze-thaw cycles. |

| Other Names | Fibroblast growth factor 21, FGF-21, Fgf21 |
| Target Background | 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 (a.a.) 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. |

| Name | Fgf21 |
|---|---|
| Function | Stimulates glucose uptake in differentiated adipocytes via the induction of glucose transporter SLC2A1/GLUT1 expression (but not SLC2A4/GLUT4 expression). Activity probably requires the presence of KLB. Regulates systemic glucose homeostasis and insulin sensitivity. |
| Cellular Location | Secreted. |
| Tissue Location | Most abundantly expressed in the liver, also expressed in the thymus at lower levels (PubMed:10858549, PubMed:30389664). Expressed in skeletal muscle (at protein level) Secreted in plasma (at protein level) (PubMed:30605666) |
