狗 Neuregulin-1蛋白|Neuregulin-1 protein|Neuregulin-1(Canine, C-His)（产品说明）
蛋白名称：Neuregulin-1蛋白, Neuregulin-1 protein
蛋白构建：A DNA sequence encoding the canine NRG1 (XP_858147.1) extracellular domain (Ser19-Lys240) was expressed with a C-terminal polyhistidine tag.
表达宿主：HEK293 Cells
蛋白纯度：> 90 % as determined by SDS-PAGE
蛋白活性：Measured in a serum-free cell proliferation assay using MCF‑7 human breast cancer cells. The ED50 for this effect is typically 0.2-2 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：Ser 19
蛋白分子量：The recombinant canine NRG1 comprises 233 amino acids and has a predicted molecular mass of 25.5 kDa. The apparent molecular mass of the protein is approximately 39-46 kDa in SDS-PAGE under reducing conditions due to glycosylation.
蛋白NP号：XP_858147.1
蛋白氨基酸序列：Ser19-Lys240
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.
