| 檢索號 | Q13261-3 |
| 分子量 | 42.2 kDa |
| 表觀分子量 | 60-75 kDa |
| 標簽 | C-Fc |
| 生物活性 | Measured by its ability to block human IL-15-induced proliferation of CTLL-2 mouse cytotoxic T cells. The ED50 for this effect is 0.35-3.5 ng/mL. |
| 純度 | > 95% as determined by reducing SDS-PAGE. |
| 內(nèi)毒素 | < 0.1 |
| 儲存條件 | Lyophilized protein should be stored at -5~-20℃, stable for one year after receipt. Reconstituted protein solution can be stored at 2-8℃ for 2-7 days. Aliquots of reconstituted samples are stable at -5~-20℃ for 3 months. |
| 運輸條件 | Ambient temperature or ice pack. |
| 有效期 | 12個月 |
| 制劑 | Lyophilized from a 0.2 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.4. |
| 復融 | Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/mL. Dissolve the lyophilized protein in sterile water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. |
| 背景介紹 | Interleukin 15 Receptor alpha (IL-15Rα) is a transmembrane glyco Protein that plays a pleiotropic role in immune development and function, including the positive maintenance of lymphocyte homeostasis. IL-15Rα chain can bind soluble IL-15 and "transpresent" Cytokine to the cells, allowing them to respond to IL-15. Soluble IL-15Rα can function as a specific high-affinity IL-15 antagonist. The soluble IL-15/IL-15Rα complexes exhibit a strong agonistic activity which is mediated through membrane-bound IL-15 Receptor β and γ heterodimers and enables signaling to cells. |

Q1:官網(wǎng)的因子都是不含動物成分的么？
我們公司的因子都是重組的，是不含動物源成分的。
-
Q2:細胞因子用無菌水配成了100ug/mL母液，用于實驗時，需要的終濃度為10ng/mL，可以用培養(yǎng)基直接稀釋？還是需要通過PBS（含5%海藻糖）進一步稀釋才行呢？
如果是直接做實驗，可以直接添加培養(yǎng)基進行稀釋配置。 如果是需要長時間保存的話，需要使用含載體蛋白(如0.1%BSA，10% FBS，5%HSA或5%海藻糖)的溶液進一步釋后分裝保存于-5~-20℃或者-80℃冰箱
-
Q3:細胞因子加無菌水溶解后需要再次離心嗎？
加了無菌水后，如果沒有掛壁現(xiàn)象是不用離心的，如果您放置了一段時間，再次使用時是可以使用離心機離心的
-
Q4:細胞因子離心前需要放置室溫嗎？
不用提前放置室溫.
