| 復(fù)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 | The IL-17 family include IL-17A, IL-17B, IL-17C, IL-17D, IL-17E (also called IL-25), and IL-17F. The family is comprised of at least six proinflammatory Cytokines that share a conserved cysteine-knot structure but diverge at the N-terminus. All members of the IL-17 family have a similar Protein structure, with four highly conserved cysteine residues critical to their 3-dimensional shape, yet they have no sequence similarity to any other known Cytokines. IL-17 family members are glyco Proteins secreted as dimers that induce local Cytokine production and recruit granulocytes to sites of inflammation. IL-17 is induced by IL-15 and IL-23, mainly in activated CD4+ T cells distinct from Th1 or Th2 cells. IL-17F is the most homologous to IL-17, but is induced only by IL-23 in activated monocytes. |

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.
