| 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 | Human IL-2RB, also known asInterleukin-2 Receptor subunit beta,is the Receptor for Interleukin-2. IL2 Receptor complex is involved in Receptor mediated endocytosis and transduces the mitogenic signals of IL2. IL2 Receptor complex has three forms with respect to ability to bind IL2. IL-2RB is belonged to a type I membrane Protein,and has a 26 residue signal peptide, a 214 residue extracellular region, a 25 residue transmembrane region and a 286 residue cytoplasmic domain. IL-2RB is the subunit critical for Receptor-mediated signaling via physically or functionally coupling to other signaling molecules, such as the Jak-STAT and Src-family Protein tyrosine kinase although it lacks apparent catalytic Motifs. |

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.
