简单介绍
重组小鼠制瘤素M.蛋白与其它公司提供的重组蛋白不同，rMuOSM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.重组小鼠制瘤素M.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.

Reconstitution
|
重组小鼠制瘤素M.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
|
Oncostatin M (OSM) is a multifunctional cytokine that belongs to the Interleukin-6 subfamily. Among the family members, OSM is most closely related to leukemia inhibitory factor (LIF) and it in fact utilizes the LIF receptor in addition to its specific receptor in the human. A biologically active OSM receptor has been previously described that consists of a heterodimer of leukemia inhibitory factor receptor (LIFR) and gp130. OSM is synthesized by stimulated T-cells and monocytes. Furthermore, the effects of OSM on endothelial cells suggest a pro-inflammatory role for OSM and endothelial cells possess a large number of OSM receptors. Recombinant murine OSM contains 181 amino acids and has a molecular mass of 20.4 kDa. It has approximately 48 % and 72 % amino acid sequence identity with human and rat OSM.
