| 背景介紹 | Interleukin-4 Receptor subunit alpha (IL-4RA), alos known as Soluble IL-4 Receptor subunit alpha, belongs tothe type I Cytokine Receptor family and type 4 subfamily. It expressed in both Th1 and Th2 cells. It functionsas Receptor for both Interleukin 4 and Interleukin 13 and couples to the JAK1/2/3-STAT6 pathway. The IL4response is involved in promoting Th2 differentiation. The IL4/IL13 responses are involved in regulating IgEproduction and Chemokine and mucus production at sites of allergic inflammation. In certain cell types, IL-4RA can signal through activation of insulin Receptor substrates, IRS1/IRS2. The functional IL4 Receptor isformed by initial binding of IL4 to IL4R. Subsequently it recruits to the complex of the common gammachain. In immune cells, IL-4RA creates a type I Receptor. In non-immune cells, it forms a type II Receptorwith of IL13RA1. IL4R can also interact with the IL13/IL13RA1 complex to form a similar type II Receptor andinteracts with the SH2-containing phosphatases, PTPN6/SHIP1, PTPN11/SHIP2 and INPP5D/SHIP. |

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.
-
Q5:收到細胞因子產(chǎn)品用什么溶劑復(fù)融？
1、細胞因子產(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)的溶液進一步稀釋后分裝冷凍保存即可；
