產(chǎn)品詳情
簡單介紹：
重組鼠白介素-1α蛋白與其它公司提供的重組蛋白不同，rMuIL-1α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.同時獨(dú)有的全自動蛋白純化技術(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.重組鼠白介素-1α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 | > 97 % by SDS-PAGE and HPLC analyses. |
| Biological Activity | 重組鼠白介素-1α蛋白Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using murine D10S cells is less than 2 pg/ml, corresponding to a specific activity of > 5.0 × 108 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-1α as determined by LAL method. |
| Reconstitution | 重組鼠白介素-1α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-1 alpha (IL-1α) is a non-secreted proinflammatory cytokine produced mainly by activated macrophages, as well as neutrophils, epithelial cells, and endothelial cells. It possesses metabolic, physiological, haematopoietic activities, and plays one of the central roles in the regulation of the immune responses. Both IL-1α and IL-1β binds to the same receptor and has similar if not identical biological properties. Among various species,the amino acid sequence of mature IL-1α s conserved 60 % to 70 % and human IL1 has been found to be biologically active on murine cell lines . |
