Reconstitute the lyophilized recombinant Human Fibroblast Growth Factor 21 (rHuFGF-21) to 0.1-1.0 mg/mL using sterile distilled water or aqueous buffer containing 0.1 % BSA. Storage & Stability
Lyophilized recombinant Human Fibroblast Growth Factor 21 (rHuFGF-21) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage. Shipping
Room temperature in continental US; may vary elsewhere. Background
Human Fibroblast Growth Factor 21 (FGF21) acts in an endocrine mannerand and is a metabolic regulator with pleiotropic effects. FGF21 possesses protective effects in the cardiovascular system, primarily due to metabolic effects other thanmaintaining energy homoeostasis. FGF21 is also involved inseveral processes, including reducing arteriosclerotic plaque formation in major vessels and protecting themyocardium from injuries caused by infarction, ischaemia-reperfusion, isoproterenol-induced hypertrophy anddiabetic lipotoxicity. In addition, FG2F1 induces these effects by atten-uating remodelling-related in?ammation and oxidativestress and promoting myocardial energy metabolism, as well as by preventing lipid- or diabetes-induced cardiaccell apoptosis. FGF21 functions via its interaction with FGF receptors (FGFRs), with the assistance of the co-receptor β-Klotho. Structurally, the FGFRs are divided into four isoforms, FGFR1-FGFR4[1]. |
