| 背景描述 | Glial cell line-derived neurotrophic factor (GDNF) is the neurotrophic factor, belonging to the GDNF family of ligands (GFL) and identifying as a therapeutic candidate in Parkinson's disease. GDNF is a 23.7 kDa protein containing 211 residues that plays a critical role in promoting the survival and differentiation of midbrain dopamine neurons. Besides, GDNF is revealed to facilitate the development of peripheral tissues such as kidney, pancreas and lung. Additionally, as a member of GFL, GDNF also takes part in the progression of tumor. |

| 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. |
