IL-23R 蛋白, Human (HEK293, Fc)

IL-23R Protein, critical in immune response, forms the interleukin-23 receptor by associating with IL12RB1. Binding to IL23, it activates T-cells, NK cells, and potentially macrophage/myeloid cells through Jak-Stat signaling. Associated with autoimmune diseases and tumorigenesis, IL-23R, in the presence of IL12RB1, forms a heterodimeric IL-23 receptor, interacting with JAK2 and activating STAT3. IL-23R Protein, Human (HEK293, Fc) is the recombinant human-derived IL-23R protein, expressed by HEK293 , with C-hFc labeled tag.

白细胞介素 23 受体 (IL-23R) 在免疫反应中发挥着关键作用，因为它通过与 IL12RB1 结合形成白细胞介素 23 受体。它与 IL23 结合，并通过 Jak-Stat 信号级联触发 T 细胞、NK 细胞以及潜在的某些巨噬细胞/骨髓细胞的激活。IL23 参与先天性免疫和适应性免疫，并且可能有助于外周组织对感染的急性反应。此外，IL23 与自身免疫性炎症性疾病有关，并已被证明在肿瘤发生中发挥重要作用。当 IL12RB1 存在时，IL-23R 形成异二聚体，充当 IL-23 受体。它与 JAK2 相互作用，并且在 IL23 存在的情况下激活 STAT3。IL23/IL-23R 促进 T 辅助细胞 1 和 T 辅助细胞 17 的分化和促炎细胞因子的分泌，从而增加宿主的杀菌活性^[1][2][3]。

1. Measured by its binding ability in a functional ELISA. Immobilized human IL23A-His+IL12B-His at 10 μg/mL (100 μl/well) can bind human IL23R-Fc and the EC₅₀ is 0.28-0.66 μg/mL.
2. Measured by its binding ability in a functional ELISA. Immobilized mouse IL12Bh (m)+mIL23Ah at 10 μg/mL (100 μl/well) can bind human IL23R-Fc. The EC₅₀ of human IL23R-Fc is 0.14-0.35 μg/mL.
3.Measured in a cell proliferation assay using M-NFS-60 cells. The ED₅₀ this effect is 0.9517 μg/mL, corresponding to a specific activity is 1.05×10³ units/mg in the presence of 0.125 ng/mL of recombinant human G-CSF.
4. Measured by its ability to inhibit IL-23 induced IL-17 secretion by Jurkat cells. The ED₅₀ for this effect is 0.03289 μg/mL in the presence of 1 ng/mL IL-23, corresponding to a specific activity is 3.04×10⁴ U/mg.

  Greater than 90% as determined by reducing SDS-PAGE

无菌粉末.

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4 or 20 mM PB, 150 mM NaCl, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
