蛋白名称:Human SHH / Sonic hedgehog Protein (aa 1-197, His Tag)
蛋白构建:A DNA sequence encoding the amino acid sequence (Met 1-Gly 197) of human SHH (Q15465), that is Sonic hedgehog protein N-product, was fused with a polyhistidine tag at the C-terminus.
表达宿主:HEK293 Cells
蛋白纯度:> 95 % as determined by SDS-PAGE
蛋白活性:Measured by its ability to induce alkaline phosphatase production by C3H10T1/2 mouse embryonic fibroblast cells. Nakamura, T. et al. (1997) Biochem. Biophys. Res. Commun.237:465. The ED50 for this effect is typically 2-10 μg/mL.
蛋白内毒素:< 1.0 EU per μg of the protein as determined by the LAL method
预测N端:Cys 24
蛋白分子量:The recombinant human SHH (aa 1-197) consists of 185 amino acids and has a predicted molecular mass of 21 kDa. The apparent molecular mass of the protein is approximately 24 kDa in SDS-PAGE under reducing conditions due to glycosylation.
蛋白NP号:Q15465
蛋白氨基酸序列:Met1-Gly197
蛋白标签:C-His
蛋白保存条件:Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

Application of Sonic Hedgehog to the Developing Chick Limb
Here, we describe methods for applying Sonic hedgehog (Shh) to developing chick limbs. The Sonic hedgehog gene is expressed in the polarizing region, a signaling region at the posterior margin of the limb bud and application of Shh-expressing
HIS 标签蛋白纯化效果不理想,宝宝心里苦呀。今天,小编来跟大家一起找找原因。 纯化所得组分中没有收集到重组的 HIS 标签蛋白。该问题主要可以分为以下两个方面: 1、HIS 标签蛋白没有结合到填料上就流穿了 原因一 超声的功率不对。超声功率过高,容易导致蛋白炭化;功率过低,蛋白释放不出来。 建议 改变超声功率,同时可以在超声前加入溶菌酶。 原因二 结合缓冲液条件不合适。 建议 检查结合缓冲液中是否有影响结合的因素,如:金属离子螫合剂、强还原剂、过高的咪唑浓度。同时,优化缓冲
