重组人 ICOS / AILIM / CD278 蛋白 (His & Fc标签)（产品说明）
蛋白名称：Human ICOS / AILIM / CD278 Protein (His & Fc Tag)
蛋白构建：A DNA sequence encoding the extracellular domain of human ICOS (NP_036224.1) (Met 1-Phe 141) was fused to 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 binding ability in a functional ELISA . Immobilized human human B7-H2 at 1 μg/ml (100 μl/well) can bind human ICOS with a linear range of 1.6-200 ng/ml.
蛋白内毒素：< 1.0 EU per μg of the protein as determined by the LAL method
预测N端：Glu 21
蛋白分子量：The recombinant human ICOS/Fc is a disulfide-linked homodimeric protein. The reduced monomer consists of 368 amino acids and predicts a molecular mass of 41.6 kDa. The apparent molecular mass of rhICOS/Fc monomer is approximately 50 kDa due to glycosylation.
蛋白NP号：NP_036224.1
蛋白氨基酸序列：Met1-Phe141
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.
