产品详情
简单介绍：
重组鼠心肌营养素1蛋白与其它公司提供的重组蛋白不同，rMuCT-1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.重组鼠心肌营养素1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 | > 95 % by SDS-PAGE and HPLC analyses. |
| Biological Activity | 重组鼠心肌营养素1蛋白Fully biologically active when compared to standard. The ED50as determined by a cell proliferation assay using human TF-1 cells is less than 0.5 ng/ml, corresponding to a specific activity of > 2.0 × 106IU/mg. |
| Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation | Lyophilized from a 0.2 µm filtered concentrated solution in 20 mM Tris, 300 mM NaCl, pH 8.5. |
| Endotoxin | Less than 1 EU/µg of rMuCT-1 as determined by LAL method. |
| Reconstitution | 重组鼠心肌营养素1蛋白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 | Cardiotrophin1 (CT1) is a member of the cytokine family which also includes IL-6, IL-11, leukemia inhibitory factor (LIF), oncostatin M (OSM), and ciliary neurotrophic factor (CNTF). CT-1 is a pleiotropic cytokine which is expressed in various tissues including the ***** heart, skeletal muscle, ovary, colon, prostate and fetal lung. In addition, CT-1 which induces cardiac myocyte hypertrophy in vitro can bind to and activate the ILST/gp130 receptor. Murine CT1 encodes a 203 amino acid (a.a.) residue protein that lacks a hydrophobic signal peptide. Human and murine CT1 share 80 % a.a. sequence identity and exhibit cross-species activity. |
