背景描述 | Transforming Growth Factors beta 1 (TGF beta 1) is the cytokine of the TGF-beta family, which is a 12.5 kDa protein containing 113 amino acid residues. TGF beta 1 is produced by white blood cell which plays an important role in inflammation, cell proliferation and differentiation. TGF beta 1 also has several functions about cancer and auto-immune diseases. TGF-beta 1 not only can activate the smad signaling but also can induce the MAPK, Rhoa and RAS. |

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. |
