| 內(nèi)毒素 | < 0.1 EU per 1 μg of the protein by the LAL method. |
| 儲存條件 | 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 8.0. |
| 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 | RANKL and RANK are members of the TNF superfamily of ligands and receptors that is critical for the regulation of specific immunity and bone turnover. RANK receptor was originally identified as a dendritic cell-membrane protein, which, by interacting with RANKL, augments the ability of dendritic cells. These dendritic cells then stimulate na?ve T-cell proliferation in a mixed lymphocyte reaction, promote the survival of RANK+ T-cells, and regulate T-cell-dependent immune response. RANKL, which is expressed in a variety of cells, including osteoblasts, fibroblasts, activated T-cells and bone marrow stromal cells, is also capable of interacting with a decoy receptor called OPG. |

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(xì)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(jìn)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(jìn)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(jìn)一步釋后分裝保存于-5~-20℃或者-80℃冰箱
-
Q3:細(xì)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(xì)胞因子離心前需要放置室溫嗎？
不用提前放置室溫.
-
Q5:因子到貨了，里面有兩管溶液，一個是水，一個是海藻糖溶液，用哪一個稀釋呢？
1、將裝有細(xì)胞因子的管子放入小離心機內(nèi)短暫離心20~30s（離心機最大轉(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，注意計算溶解后濃度不低于100 μg/mL； 3、用贈送的含海藻糖的PBS溶液進(jìn)一步稀釋到您實驗合適的濃度即可，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。

Q6:收到細(xì)胞因子產(chǎn)品用什么溶劑復(fù)融？
1、細(xì)胞因子產(chǎn)品大部分為凍干形式發(fā)貨，少部分液體形式發(fā)貨； 2、凍干粉狀態(tài)的因子產(chǎn)品需指定溶劑復(fù)溶，請參考產(chǎn)品說明書【復(fù)融】方法，按照要求使用對應(yīng)溶劑溶解，大部分因子為無菌水復(fù)融，少部分需要無菌水以外的特殊溶劑溶解的產(chǎn)品則隨貨會贈送相應(yīng)的復(fù)融試劑；凍干粉溶解后如您需要進(jìn)一步稀釋分裝，需使用含載體蛋白(如0.1% BSA，10%FBS，5%HSA 或 5% 海藻糖)的溶液進(jìn)一步稀釋后分裝冷凍保存。 3、液體形式因子產(chǎn)品不需要復(fù)溶，具體濃度詳見產(chǎn)品標(biāo)簽，按照實驗需要用含載體蛋白(如0.1% BSA，10%FBS，5%HSA 或 5% 海藻糖)的溶液進(jìn)一步稀釋后分裝冷凍保存即可；
