IL-13R alpha 2 蛋白, Human (HEK293, His)

IL-13R alpha 2 Protein, functioning as a monomer, exhibits high-affinity binding exclusively to interleukin-13 (IL13) without interaction with interleukin-4 (IL4). This binding selectivity indicates a unique role and specificity for IL-13R alpha 2 in mediating cellular responses to IL13, emphasizing its importance in IL13-associated cellular processes. IL-13R alpha 2 Protein, Human (HEK293, His) is the recombinant human-derived IL-13R alpha 2 protein, expressed by HEK293, with C-His labeled tag. The total length of IL-13R alpha 2 Protein, Human (HEK293, His) is 316 a.a., with molecular weight of 46-50 kDa.

IL-13R α2 蛋白作为具有高亲和力的单体发挥作用，特异性结合白细胞介素 13 (IL13)，但不结合白细胞介素 4 (IL4)。这种结合选择性表明 IL-13R α2 在介导 IL13 反应中具有独特的作用和特异性，突出了其在与该细胞因子相关的细胞过程中的重要性。

Measured by its ability to inhibit IL-13-dependent proliferation of TF-1 human erythroleukemic cells.The ED₅₀ for this effect is 0.053 μg/mL in the presence of 8 ng/mL recombinant human IL-13, corresponding to a specific activity is 1.880×10⁴ U/mg.
