| 生物活性 | Measure by its ability to chemoattract BaF3 cells transfected with human CCR5. The ED50 for this effect is < 10 ng/mL. |
| 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(chǔ)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. |
| 運(yùn)輸條件 | Ambient temperature or ice pack. |
| 有效期 | 12個(gè)月 |
| 制劑 | The protein was lyophilized from a 0.2 μm filtered solution containing 50 mM Tris and 150 mM NaCl, pH 8.5. |
| 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 | CCL3 is belonging to the CC chemokine family. CCL3 participates in activating and recruiting cells, such as lymphocytes, monocytes, and granulocytes during acute inflammation. In addition, CCL3 can enhance IFN-γ secretion from activated T cells and thus induces Th1 response, thereby to regulating leukocyte migration. It is reported that CCL3 is involved in susceptibility of HIV infection and disease progression of AIDS. |

Q1:官網(wǎng)的因子都是不含動(dòng)物成分的么？
我們公司的因子都是重組的，是不含動(dòng)物源成分的。

Q2:細(xì)胞因子用無(wú)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(guò)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(zhǎng)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(wú)菌水溶解后需要再次離心嗎？
加了無(wú)菌水后，如果沒(méi)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.
