| 儲(chǔ)存條件 | Lyophilized protein should be stored at -5~-20℃ for 1 year. Upon reconstitution, store at 2-8℃ for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1% BSA, 10% FBS, 5% HSA or 5% trehalose solution), protein aliquots should be stored at -5~-20℃ or -80℃ for 3-6 months. |

| 制劑 | The protein was lyophilized from a 0.2 μm filtered solution containing 1 × PBS, pH 7.4. |
| 復(fù)融 | It is recommended to reconstitute the lyophilized protein in sterile water to a concentration not less than 100 μg/mL. Do Not Vortex! Vigorous shaking may impair the biological activity of the protein. |
| 背景介紹 | Interleukin-2 (IL-2) is an interleukin, a type of cytokine signaling molecule in the immune system. It is a 15,5 -16 kDa protein that regulates the activities of white blood cells (leukocytes, often lymphocytes) that are responsible for immunity. IL-2 is part of the body's natural response to microbial infection, and in discriminating between foreign ("non-self") and "self". IL-2 mediates its effects by binding to IL-2 receptors, which are expressed by lymphocytes. |

Q1:因子到貨了，里面有兩管溶液，一個(gè)是水，一個(gè)是海藻糖溶液，用哪一個(gè)稀釋呢？
1、將裝有細(xì)胞因子的管子放入小離心機(jī)內(nèi)短暫離心20~30s（離心機(jī)最大轉(zhuǎn)速即可），使附著在管壁的微量蛋白聚集在管底； 2、先用無菌水溶解因子，很少量水即可溶解因子，注意計(jì)算溶解后濃度不低于100 μg/mL； 3、用贈(zèng)送的含海藻糖的PBS溶液進(jìn)一步稀釋到您實(shí)驗(yàn)合適的濃度即可，然后分裝后放入-20℃以下保藏； 4、因子復(fù)融重懸過程應(yīng)輕柔，不可以震蕩渦旋。
