產(chǎn)品詳情
簡(jiǎn)單介紹：
重組鼠白細(xì)胞介素-3蛋白與其它公司提供的重組蛋白不同，rMuIL-3蛋白產(chǎn)品為采用CFS的無(wú)細(xì)胞麥胚蛋白合成系統(tǒng)表達(dá)出來(lái)的重組蛋白，可表達(dá)出對(duì)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(jiǎn)便高效，將蛋白純化過(guò)程中對(duì)蛋白的損傷降低到*小程度.重組鼠白細(xì)胞介素-3蛋白（全長(zhǎng)序列）產(chǎn)品可用于Western Blot驗(yàn)證、抗體制備、蛋白檢測(cè)、ELISA等試驗(yàn)中.

| Purity | 重組鼠白細(xì)胞介素-3蛋白> 98 % by SDS-PAGE and HPLC analyses. |
| Biological Activity | Fully biologically active when compared to standard. The ED50 as determined by the dose-dependent stimulation of the proliferation of murine M-NFS-60 cells is less than 0.05 ng/ml, corresponding to a specific activity of > 2 × 107 IU/mg. |
| Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation | Lyophilized from a 0.2 μm filtered solution in PBS, pH 7.4. |
| Endotoxin | Less than 1 EU/μg of rMuIL-3 as determined by LAL method. |
| Reconstitution | 重組鼠白細(xì)胞介素-3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 | Interleukin-3 (IL-3) is a type of biological signal (cytokine) which is encoded by the IL-3 gene located on chromosome 5 and produced primarily by activated T cells beside human thymic epithelial cells, activated murine mast cells, murine keratinocytes and neurons/astrocytes. The protein acts in hematopoiesis by controlling the production, differentiation, and function of 2 related white cell populations of the blood, the granulocytes and the monocytes-macrophages. In addition, it exerts its biological activities through binding to interleukin-3 receptors included α and β subunits. The Mouse IL-3 is different from human IL-3 and contains 140 amino acids residues. Specifically, mouse and human IL-3 share low homology and have not cross species activity. |
