生物活性 | Measure by its ability to induce MC/9-2 cells proliferation. The ED50 for this effect is < 1 ng/mL. The specific activity of recombinant mouse IL-10 is > 1 × 10^6 IU/mg. |
純度 | > 98% as determined by SDS-PAGE. Ni-NTA chromatography. |
內(nèi)毒素 | < 0.1 EU per 1 μg of the protein by the LAL method. |
儲存條件 | Lyophilized protein should be stored at -5~-20℃ for 1 year. Upon reconstitution, store at 2-8℃ for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1% BSA, 10% FBS, 5% HSA or 5% trehalose solution), protein aliquots should be stored at -5~-20℃ or -80℃ for 3-6 months. |

制劑 | The protein was lyophilized from a 0.2 μm filtered solution containing 1 × PBS, pH 7.4. |
復(fù)融 | It is recommended to reconstitute the lyophilized protein in sterile water to a concentration not less than 100 μg/mL. Do Not Vortex! Vigorous shaking may impair the biological activity of the protein. |
背景介紹 | Interleukin 10 (IL-10), also known as human cytokine synthesis inhibitory factor (CSIF), is an anti-inflammatory cytokine. In humans, interleukin 10 is encoded by the IL10 gene. IL-10 signals through a receptor complex consisting of two IL-10 receptor-1 and two IL-10 receptor-2 proteins. Consequently, the functional receptor consists of four IL-10 receptor molecules. IL-10 binding induces STAT3 signalling via the phosphorylation of the cytoplasmic tails of IL-10 receptor 1 + IL-10 receptor 2 by JAK1 and Tyk2 respectively. |

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.
-
Q5:因子到貨了,里面有兩管溶液,一個(gè)是水,一個(gè)是海藻糖溶液,用哪一個(gè)稀釋呢?
1、將裝有細(xì)胞因子的管子放入小離心機(jī)內(nèi)短暫離心20~30s(離心機(jī)最大轉(zhuǎn)速即可),使附著在管壁的微量蛋白聚集在管底; 2、先用無菌水溶解因子,很少量水即可溶解因子,注意計(jì)算溶解后濃度不低于100 μg/mL; 3、用贈送的含海藻糖的PBS溶液進(jìn)一步稀釋到您實(shí)驗(yàn)合適的濃度即可,然后分裝后放入-20℃以下保藏; 4、因子復(fù)融重懸過程應(yīng)輕柔,不可以震蕩渦旋。
