| 生物活性 | Measured by its ability to inhibit TGF-beta 1 activity on TF-1 human erythroleukemic cells. The ED50 for this effect is 18.41 ng/mL in the presence of 100 pg/mL of recombinant human TGF-beta 1. |
| 純度 | > 95% as determined by reducing SDS-PAGE. |
| 內(nèi)毒素 | < 1.0 EU per 1 μg as determined by LAL test. |
| 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, 150 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 | TGFBR2 is a single-pass type I membrane Protein and contains one Protein kinase domain. TGFBR2 exsits as a heterodimeric complex with another Receptor Protein and binds TGF-beta. Signals triggered through the TGF-beta Receptor complex prompt various responses by the cell. One such response is to inhibit cell growth and division. Based on this action, the TGF-beta Receptor type 2 is sometimes called a tumor suppressor. Defects in TGFBR2 have been associated with Marfan syndrome, Loeys-Deitz aortic aneurysm syndrome, Osler-Weber-Rendu syndrome and the development of various types of tumors. |

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.
-
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；
