重组人 ACVR2B / ActivinR-IIB 蛋白 (His标签)（产品说明）
蛋白名称：Human ACVR2B / ActivinR-IIB Protein (His Tag)
蛋白构建：A DNA sequence encoding the extracellular domain of human ACVR2B (NP_001097.2) (Met 1-Thr 134) was fused with a polyhistidine tag at the C-terminus.
表达宿主：HEK293 Cells
蛋白纯度：> 97 % as determined by SDS-PAGE
蛋白活性：1. Measured by its ability to bind biotinylated Human INHBA-his (Cat:10429-H08H）in functional ELISA. 2. Measured by its ability to bind biotinylated Mouse INHBA-his (Cat:50659-M08H) in functional ELISA. 3. Measured by its ability to neutralize Activin-mediated inhibition on MPC11 cell proliferation. The ED50 for this effect is typically 0.3-2 µg/mL in the presence of 10 ng/mL recombinant Activin A.
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 human ACVR2B comprises 127 amino acids and predicts a molecular mass of 15 kDa. As a result of glycosylation, rh ACVR2B migrates as an approximately 33-38 kDa protein in SDS-PAGE under reducing conditions.
蛋白NP号：NP_001097.2
蛋白氨基酸序列：Met1-Thr134
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.
