Description : | Fibroblast growth factor 21 (FGF-21) encoded by the FGF-21 gene belongs to the large FGF family and it is specifically induced by HMGCS2 activity. In mice, brown adipose tissue becomes a source of systemic FGF-21 after cold exposure. FGF-21 stimulates glucose uptake in differentiated adipocytes via the induction of glucose transporter SLC2A1/GLUT1 expression (but not SLC2A4/GLUT4 expression) and the activity depends on the presence of KLB. Recombinant rat FGF-21 contains 180 amino acids residues and show limited binding to heparin. In addition, rat FGF-21 respectively shows 81 % and 92 % a.a. identity to human and murine FGF-21, and it show activity on murine and human cells. |
Source : | E.coli |
Species : | Rat |
Form : | Lyophilized from a 0.2μm filtered concentrated solution in PBS, 500 mM NaCl, pH 7.4. |
Bio-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 µg/ml of rMuKlotho-β and 10 μg/ml of heparin. |
Molecular Mass : | Approximately 19.7 kDa, a single non-glycosylated polypeptide chain containing 180 amino acids. |
Protein length : | 180 |

Endotoxin : | Less than 1 EU/µg of rRtFGF-21 as determined by LAL method. |
Purity : | >95% by SDS-PAGE and HPLC analysis. |
Storage : | Use a manual defrost freezer and avoid repeated freeze-thaw cycles. 12 months from date of receipt, -20 to -70 centigrade as supplied. 1 month, 2 to 8 centigrade under sterile conditions after reconstitution. 3 months, -20 to -70 centigrade under sterile conditions after reconstitution. |
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 centigrade. Further dilutions should be made in appropriate buffered solutions. |

Ask a questionFGF21 expression in adipose tissue is regulated by various factors, including peroxisome proliferator-activated receptor gamma (PPARγ) activation.
FGF21 influences lipid metabolism by promoting the utilization of fatty acids for energy, contributing to the regulation of lipid homeostasis.
FGF21 levels are being explored as potential biomarkers for metabolic health, reflecting conditions such as insulin resistance and metabolic syndrome.
Yes, FGF21 plays a role in improving insulin sensitivity, making it a potential target for interventions in insulin resistance-associated conditions.
Yes, FGF21 influences energy expenditure by promoting thermogenesis in brown adipose tissue, contributing to overall metabolic regulation.
Gender-specific differences in FGF21 levels have been reported, with some studies suggesting higher circulating FGF21 concentrations in females.
FGF21 activates signaling pathways such as the AMP-activated protein kinase (AMPK) pathway, which contributes to its metabolic effects.
