简单介绍

重组鼠白介素-1α蛋白与其它公司提供的重组蛋白不同，rMuIL-1α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-1α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.

Biological Activity	重组鼠白介素-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	重组鼠白介素-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 .
