简单介绍:
重组大鼠白细胞介素-1 beta蛋白与其它公司提供的重组蛋白不同,rRtIL-1β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.重组大鼠白细胞介素-1 beta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 重组大鼠白细胞介素-1 beta蛋白Fully biologically active when compared to standard. The ED50as determined by a cell proliferation assay using murine D10S cells is less than 0.1 ng/ml, corresponding to a specific activity of > 1.0 × 107IU/mg.
Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation Lyophilized from a 0.2 µm filtered concentrated solution in PBS, pH 7.4, with 5 % trehalose, 0.02 % Tween-20.
Endotoxin Less than 1 EU/µg of rRtIL-1β as determined by LAL method.
Reconstitution 重组大鼠白细胞介素-1 beta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-1beta (IL-1β) 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-1αand IL-1β binds to the same receptor and has similar but not identical biological properties. The mature rat IL1β shares 90 % a.a. sequence identity with cotton rat and mouse and 65 % to 77 % with canine, human,and rhesus IL1β.
