背景描述 | Fibroblast Growth Factors 21 (FGF-21) is a 23 kDa protein with 210 amino acid residues. Belongs to FGF superfamily, FGF-21 is related to glucose and lipid metabolism. Peroxisome proliferator-activated receptor gamma (PPARg) and peroxisome proliferator-activated receptor alpha (PPARa) regulate FGF-21 expression. |

分子量 | The protein has a calculated MW of 20.76 kDa. The protein migrates as 25-35 kDa under reducing condition (SDS-PAGE analysis). |
表达系统 | Escherichia coli |
纯度 | >98% as determined by SDS-PAGE. |
生物活性 | Measure by its ability to induce proliferation in NIH‑3T3 mouse embryonic fibroblast cells in the presence of mouse Klotho beta and heparin. The ED₅₀ for this effect is < 2 μg/mL. |
内毒素检测 | <0.1 EU per 1 μg of the protein by the LAL method. |

储存 | Lyophilized protein: Store at -20°C for 1 year. After reconstitution: · Store at 2°C to 8°C for up to 1 week. · For extended storage (beyond 1 week), dilute the reconstituted protein in a buffer containing a carrier protein or stabilizer (e.g., 0.1% BSA, 10% FBS, 5% HSA, or 5% trehalose solution). The final concentration is not less than 10 μg/ml. Prepare aliquots (≥20 μl) and store at -20°C or -80°C for 3 to 6 months. Avoid repeated freeze-thaw cycles. |
