| 儲(chǔ)存條件 | Lyophilized protein should be stored at -5~-20℃, stable for one year after receipt. Reconstituted protein solution can be stored at 2-8℃ for 2-7 days. Aliquots of reconstituted samples are stable at -5~-20℃ for 3 months. |
| 運(yùn)輸條件 | Ambient temperature or ice pack. |
| 有效期 | 12個(gè)月 |
| 制劑 | Lyophilized from a 0.2 μm filtered solution of 20 mM PB, 250 mM NaCl, pH 7.2. |
| 復(fù)融 | Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/mL. Dissolve the lyophilized protein in sterile water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. |
| 背景介紹 | Neurotrophin-3 (NT-3) is a member of the NGF family of neurotrophic factors and is structurally related to β-NGF, BDNF and NT-4. The NT3 cDNA encodes a 257 amino acid residue precursor Protein with a signal peptide and a pro Protein that are cleaved to yield the 119 amino acid residue mature NT3.The amino acid sequences of mature human, murine and rat NT-3 are identical. NT-3 selectively promotes the differentiation and survival of specific neuronal subpopulations in both the central as well as the peripheral nervous systems. |

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(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.
