重组人 HER3 / ErbB3 蛋白 (ECD, His标签)(产品说明)
蛋白名称:Human HER3 / ErbB3 Protein (ECD, His Tag)
蛋白构建:A DNA sequence encoding the extracellular domain (Met 1-Thr 643) of human ErbB3 (NP_001973.2) precursor was expressed, with a C-terminal polyhistidine tag.
表达宿主:HEK293 Cells
蛋白纯度:> 95 % as determined by SDS-PAGE
蛋白活性:1. Measured by its binding ability in a functional ELISA. 2. Immobilized human ErbB3 at 2 μg/mL (100 μl/well) can bind human NRG1 (isoform Beta1), The EC50 of human NRG1 (isoform Beta1) is 0.43 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 20
蛋白分子量:The recombinant human ErbB3 protein consists of 635 amino acids after the removal of signal peptide and has a calculated molecular mass of 70.2 kDa. As a result of glycosylation, the recombinant ErbB3 migrates as an approximately 100-110 kDa band in SDS-PAGE under reducing conditions.
蛋白NP号:NP_001973.2
蛋白氨基酸序列:Met1-Thr643
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.
