| 生物活性 | Measure by its ability to induce alkaline phosphatase production by ATDC5 cells. The ED50 for this effect is < 17 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 20 mM sodium citrate, 0.2 M NaCl, pH 3.5. |
| 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 | Bone morphogenetic protein 15 is a protein, that in humans, is encoded by the BMP15 gene. It's mainly involved in folliculogenesis. The protein encoded by this gene is a member of the TGF-β superfamily. It is a paracrine signaling molecule involved in oocyte and follicular development. Using Northern blot analysis, BMP15 has been shown to be exclusively expressed in the ovaries. This protein may be involved in oocyte maturation and follicular development as a homodimer or by forming heterodimers with a related protein, Gdf9. |

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.
