制劑 | Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4. |
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 | Tumor necrosis factor Receptor superfamily member 1B (TNFRSF1B) is a member of the tumor necrosisfactor Receptor superfamily. Human TNF RII contains four cysteinerich repeats in its ECD, which shares 58% and 56% amino acid sequence identity with the mouse and rat orthologs, respectively.TNF RII is expressedpredominantly on cells of the hematopoietic lineage, such as T and natural killer cells, as well as onendothelial cells, microglia, astrocytes,neurons, oligodendrocytes, cardiac myocytes, thymocytes, andmesenchymal stem cells. TNF RII binds to the membranebound forms of TNFα and Lymphotoxinα/TNFβ; soluble TNF is thought to signal predominately through TNF RI.Soluble TNF RII is believed to inhibit TNFbiological activity by binding TNF thereby preventing it from activating membrane TNF Receptors. |

Q1:官網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.
