| 背景介紹 | Interleukin-1 Receptor type 2 (IL1R2) belongs to the Interleukin-1 Receptor family. Two distinct types of IL1 Receptors which are able to bind IL1 specifically have been identified, designated as IL1RI (IL1RA) and IL1RII (IL1RB). IL1 Receptor type II is a 68 kDa transmembrane Protein found on B lymphocytes, neutrophils, monocytes, large granular leukocytes and endothelial cells. IL1R2 is non-signaling Receptor forIL1A, IL1B and IL1RN, reduces IL1B activities. IL1R2 serves as a decoy Receptor by competetive binding to IL1B and preventing its binding to IL1R1. IL1R2 modulates cellular response through non-signaling association with IL1RAP after binding to IL1B. IL1R2 (membrane and secreted forms) preferentially binds IL1B and poorly IL1A and IL1RN. The secreted IL1R2 recruits secreted IL1RAP with high affinity; this complex formation may be the dominant mechanism for neutralization of IL1B by secreted/soluble Receptors. |

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(shí)驗(yàn)時(shí)，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(shí)驗(yàn)，可以直接添加培養(yǎng)基進(jìn)行稀釋配置。 如果是需要長時(shí)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(shí)間，再次使用時(shí)是可以使用離心機(jī)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.
