| 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 PBS, 5 mM EDTA, pH 7.5. |
| 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 | Fibroblast Growth Factor 12 (FGF-12) is a member of the fibroblast Growth Factor (FGF) family. FGF-12 is probably involved in nervous system development and function. FGF-12 lacks the N-terminal signal sequence present in most of the FGF family members, but it contains clusters of basic residues that have been demonstrated to act as a nuclear localization signal. When transfectedinto mammalian cells, this Protein accumulated in the nucleus, but was not secreted. The specific function of this gene has not yet been determined. Two alternatively spliced transcript variants encoding distinct isoforms have been reported. |

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?zhuān)窟€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.
-
Q5:收到細(xì)胞因子產(chǎn)品用什么溶劑復(fù)融？
1、細(xì)胞因子產(chǎn)品大部分為凍干形式發(fā)貨，少部分液體形式發(fā)貨； 2、凍干粉狀態(tài)的因子產(chǎn)品需指定溶劑復(fù)溶，請(qǐng)參考產(chǎn)品說(shuō)明書(shū)【復(fù)融】方法，按照要求使用對(duì)應(yīng)溶劑溶解，大部分因子為無(wú)菌水復(fù)融，少部分需要無(wú)菌水以外的特殊溶劑溶解的產(chǎn)品則隨貨會(huì)贈(zèng)送相應(yīng)的復(fù)融試劑；凍干粉溶解后如您需要進(jìn)一步稀釋分裝，需使用含載體蛋白(如0.1% BSA，10%FBS，5%HSA 或 5% 海藻糖)的溶液進(jìn)一步稀釋后分裝冷凍保存。 3、液體形式因子產(chǎn)品不需要復(fù)溶，具體濃度詳見(jiàn)產(chǎn)品標(biāo)簽，按照實(shí)驗(yàn)需要用含載體蛋白(如0.1% BSA，10%FBS，5%HSA 或 5% 海藻糖)的溶液進(jìn)一步稀釋后分裝冷凍保存即可；
