重组人 IL1R2 / CD121b 蛋白 (Fc标签)（产品说明）
蛋白名称：Human IL1R2 / CD121b Protein (Fc Tag)
蛋白构建：A DNA sequence encoding the extracellular domain (Met 1-Glu 343) of human IL1 receptor type I I (IL1RII) (NP_004624.1) was expressed with C-terminal fused Fc region of human IgG1.
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. Immobilized recombinant human IL1B at 2 μg/ml (100ul/well) can bind recombinant human IL1R2-Fc with a linear range of 6.25-400 ng/ml. 2. Using the Octet RED System, the affinity constant (Kd) of IL1R2 Protein, Human, Recombinant (Fc Tag) (Cat. 10111-H02H) bound IL-1 beta Protein, Human, Recombinant (Cat. 10139-HNAE) was 6.0 nM. 3. Measured by its ability to inhibit Interferon gamma secretion by human natural killer lymphoma NK-92 cells in the presence of 500 pg/mL IL1b. The EC50 for this effect is typically 0.1-0.8 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：Phe 14
蛋白分子量：The recombinant human IL1R2/Fc is a disulfide-linked homodimer. The reduced monomer consists of 568 amino acids and has a predicted molecular mass of 64.5 kDa. As a result of glycosylation, the rh IL1R2/Fc monomer migrates as an approximately 70-75 kDa band in SDS-PAGE under reducing conditions.
