產(chǎn)品詳情
簡單介紹：
重組人類聲波刺猬N-末端蛋白與其它公司提供的重組蛋白不同，rHuSHH蛋白產(chǎn)品為采用CFS的無細(xì)胞麥胚蛋白合成系統(tǒng)表達(dá)出來的重組蛋白，可表達(dá)出對細(xì)胞有毒性、易被蛋白酶降解的蛋白；并獲得具有良好的可溶性，并有翻譯后修飾、從而部分具有功能的蛋白.同時(shí)獨(dú)有的全自動蛋白純化技術(shù)則簡便高效，將蛋白純化過程中對蛋白的損傷降低到*小程度.重組人類聲波刺猬N-末端蛋白（全長序列）產(chǎn)品可用于Western Blot驗(yàn)證、抗體制備、蛋白檢測、ELISA等試驗(yàn)中.

| Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation | Lyophilized from a 0.2 μm filtered concentrated solution in 20 mM PB, pH 7.4, 150 mM NaCl. |
| Endotoxin | Less than 1 EU/μg of rHuSHH as determined by LAL method. |
| Reconstitution | 重組人類聲波刺猬N-末端蛋白We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions. |
| Storage | This lyophilized preparation is stable at 2-8 °C, but should be kept at -20 °C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 °C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 °C to -70 °C. Avoid repeated freeze/thaw cycles. |

| Background | Sonic Hedgehog (SHH) is one of three proteins of the Hedgehog (Hh) family, which also contains Desert Hedgehog (DHH) and Indian Hedgehog (IHH). The three members share a high degree of amino-acid sequence identity (e.g., SHH and IHH are 93 % identical). SHH is expressed in fetal intestine, liver, lung, and kidney, but not in ***** tissues. The protein consists of 462 a.a. with a 23a.a. signal peptide at N-terminus, and is further cleaved into SHH N-Terminus and C-Terminus. SHH has the most critical roles in development, acting as a morphogen involved in patterning many systems, including the limb and midline structures in the brain, spinal cord, the thalamus by the zona limitans intrathalamica and the teeth. In the absence of Sonic HedgeHog, patched receptor represses the constitutive signaling activity of smoothened. SHH-N retains all known signaling capabilities, and can be lipid-modified without receptor affinity reducing, but has more potent than the unmodified form. The rHuSHH has an N-terminal Ile-Val-Ile sequence substituted for the natural occurring chemically modified Cys residue. |
