重组人 CD122 / IL-2RB 蛋白

重组人 CD122 / IL-2RB 蛋白（产品说明）
蛋白名称：Human CD122 / IL-2RB Protein
蛋白构建：The mature form of human IL2 Rβ (NP_000869.1) extracellular domain (Met 1-Asp 239) with five amino acids (DDDDK) at the C-terminus was expressed and purified.
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 IL15-dependent proliferation of MO7e human megakaryocytic leukemic cells in the presence of 4.0 ng/mL of recombinant human IL-15. The ED50 for this effect is 1-4μg/mL.
蛋白内毒素：< 1.0 EU per μg of the protein as determined by the LAL method
预测N端：Ala 27
蛋白分子量：The mature recombinant human IL2 Rβ consists of 219 amino acids and has a predicted molecular mass of 25.2 kDa. As a result of glycosylation, the rh IL2 Rβ migrates as an approximately 40 kDa protein in SDS-PAGE under reducing conditions.
蛋白NP号：NP_000869.1
蛋白氨基酸序列：Met1-Asp239
蛋白标签：C-cleavage
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.
