重组人 IL6ST / gp130 / CD130 蛋白 (His & Fc标签)（产品说明）
蛋白名称：Human IL6ST / gp130 / CD130 Protein (His & Fc Tag)
蛋白构建：A DNA sequence encoding the extracellular domain (Met 1-Ile 618) of human IL6ST (NP_002175.2) precursor was fused with the C-terminal polyhistidine-tagged Fc region of human IgG1 at the C-terminus.
表达宿主：HEK293 Cells
蛋白纯度：> 90 % as determined by SDS-PAGE.
蛋白活性：Measured by its ability to inhibit the IL-6Rα enhancement of IL-6 activity on M1 mouse myeloid leukemia cell. The ED50 for this effect is typically 0.2-0.8 μg/mL in the presence of 50 ng/mL recombinant human IL-6sR and 100 ng/mL recombinant human IL-6.
蛋白内毒素：< 1.0 EU per μg of the protein as determined by the LAL method
预测N端：Glu 23
蛋白分子量：The recombinant human IL6ST/Fc is a disulfide-linked homodimer after removal of the signal peptide. The reduced monomer consists of 844 amino acids and has a predicted molecular mass of 96 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh IL6ST/Fc monomer is approximately 125-140 kDa due to glycosylation.
蛋白NP号：NP_002175.2
蛋白氨基酸序列：Met1-Ile618
蛋白标签：C-human IgG1-Fc & 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.
