产品详情
简单介绍：
重组大鼠胶质细胞来源的神经营养因子蛋白与其它公司提供的重组蛋白不同，rRtGDNF蛋白产品为采用CFS的无细胞麦胚蛋白合成系统表达出来的重组蛋白，可表达出对细胞有毒性、易被蛋白酶降解的蛋白；并获得具有良好的可溶性，并有翻译后修饰、从而部分具有功能的蛋白.同时独有的全自动蛋白纯化技术则简便高效，将蛋白纯化过程中对蛋白的损伤降低到*小程度.重组大鼠胶质细胞来源的神经营养因子蛋白（全长序列）产品可用于Western Blot验证、抗体制备、蛋白检测、ELISA等试验中.

| Purity | 重组大鼠胶质细胞来源的神经营养因子蛋白> 98 % by SDS-PAGE and HPLC analyses. |
| Biological Activity | Fully biologically active when compared to standard. The ED50as determined by a cell proliferation assay using rat C6 cells is less than 0.2 ng/ml, corresponding to a specific activity of > 5.0 × 106IU/mg. |
| Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation | Lyophilized from a 0.2 μm filtered concentrated solution in 1 × PBS, pH 7.4. |
| Endotoxin | 重组大鼠胶质细胞来源的神经营养因子蛋白Less than 0.1 EU/μg of rRtGDNF as determined by LAL method. |
| 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 °C. Further dilutions should be made in appropriate buffered solutions. |
| Storage | This lyophilized preparation is stable at 2-8 °C, but should be kept at -20 °C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 °C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 °C to -70 °C. Avoid repeated freeze/thaw cycles. |

| Background | Glial cell-derived neurotrophic factor is a founding member of the GDNF family of ligands (GFL) and has been shown to interact with GFRA2 and GDNF family receptor alpha 1. It is a small protein that potently promotes the survival and morphological differentiation of various neuronal. It may also modulate local neuronal effects in distal regions of the motor neuron. GDNF Recombinant rat GDNF (monomer) contains 135 amino acids residues, which is a disulfide-linked homodimer and it shares 99 % and 93 % a.a. sequence identity with mouse and human GDNF. |
