产品详情
简单介绍:
重组鼠白介素-21蛋白与其它公司提供的重组蛋白不同,rMuIL-21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.重组鼠白介素-21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 | > 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 human N1186 T cells is less than 25 ng/ml, corresponding to a specific activity of > 4.0 × 104IU/mg. |
Physical Appearance | 重组鼠白介素-21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. |
Endotoxin | Less than 0.1 EU/μg of rMuIL-21 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 | 重组鼠白介素-21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. |
