| 生物活性 | Measure by its ability to induce 3T3 cells proliferation. The ED50 for this effect is < 78 ng/mL. |
| 純度 | > 95% as determined by SDS-PAGE. Ni-NTA chromatography. |
| 內(nèi)毒素 | < 0.1 |
| 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. |
| 運輸條件 | Ambient temperature or ice pack. |
| 有效期 | 12個月 |
| 制劑 | The protein was lyophilized from a 0.2 μm filtered solution containing 1 × PBS, pH 7.4. |
| 復融 | 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 | Fibroblast Growth Factor 3 (FGF-3) belongs to the large FGF family which has at least 23 members (1, 2). All FGF family members are heparin-binding growth factors with a core 120 amino acid (aa) FGF domain that allows for a common tertiary structure. Studies have suggested that FGF-3 and FGF-8 function synergistically in otic placode induction and during neuronal development to regulate dorsoventral axis formation. During development, the activities of FGF-3 and FGF-8 are regulated negatively by the sprouty family proteins and by Sef (similar expression t). |

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.
