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 | Sonic Hedgehog Homolog (SHH) belongs to a three-Protein family called hedgehog. The other two family members are Indian Hedgehog (IHH) and Desert Hedgehog (DHH). Hedgehog Proteins are key signaling molecules in embryonic development. SHH is expressed in various embryonic tissues and plays critical roles in regulating the patterning of many systems, such as limbs and brain. SHH also plays an important role in adult, including the division of adult stem cells and the development of certain cancers and other diseases. Human SHH is expressed as a 45kDa precursor, and undergoes a series of processing during secretion. After the removal of the signal peptide, a protease within the C-terminal domain catalyzes the cleavage of SHH into a 20 kDa N-terminal signaling domain (SHH-N) and a 25 kDa C-terminal domain (SHH-C). SHH-N has the "all signaling" capability. SHH-N binds to the 12 pass transmembrane Protein Patched (Ptc) on cell surface, which releases the repression of the activity of Smoothened (Smo), a G-Protein coupled Receptor, by Ptc. |

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.
