產(chǎn)品詳情
簡單介紹：
重組小鼠睫狀神經(jīng)營養(yǎng)因子蛋白與其它公司提供的重組蛋白不同，rMuCNTF蛋白產(chǎn)品為采用CFS的無細(xì)胞麥胚蛋白合成系統(tǒng)表達(dá)出來的重組蛋白，可表達(dá)出對細(xì)胞有毒性、易被蛋白酶降解的蛋白；并獲得具有良好的可溶性，并有翻譯后修飾、從而部分具有功能的蛋白.同時(shí)獨(dú)有的全自動(dòng)蛋白純化技術(shù)則簡便高效，將蛋白純化過程中對蛋白的損傷降低到*小程度.重組小鼠睫狀神經(jīng)營養(yǎng)因子蛋白（全長序列）產(chǎn)品可用于Western Blot驗(yàn)證、抗體制備、蛋白檢測、ELISA等試驗(yàn)中.

| Purity | > 95 % by SDS-PAGE and HPLC analyses. |
| Biological Activity | Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using human TF-1 cells is less than 30 ng/ml, corresponding to a specific activity of > 3.3 × 104 IU/mg. |
| Physical Appearance | 重組小鼠睫狀神經(jīng)營養(yǎng)因子蛋白Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation | Lyophilized from a 0.2 μm filtered concentrated solution in 2 × PBS, pH 7.4, 2 % trehalose. |
| Endotoxin | Less than 1 EU/μg of rMuCNTF 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 | 重組小鼠睫狀神經(jīng)營養(yǎng)因子蛋白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 | Ciliary neurotrophic factor (CNTF) is a polypeptide hormone whose actions appear to be restricted to the nervous system where it promotes neurotransmitter synthesis and neurite outgrowth in certain neuronal populations. CNTF was initially identified as a trophic factor for embryonic chick ciliary parasympathetic neurons in culture. Furthermore, the protein is also a potent survival factor for neurons and oligodendrocytes and may be relevant in reducing tissue destruction during inflammatory attacks. In addition, CNTF is useful for treatment of motor neuron disease and it could reduce food intake without causing hunger or stress. Recombinant murine CNTF containing 198 amino acids and it shares 82 % and 95 % a.a. sequence identity with human and rat CNTF. |
