| 产品描述 | IL-13 Protein, Human, Recombinant (E. coli) is expressed in E. coli. The accession number is AAK53823. |
| 生物活性 | Measured in a cell proliferation assay using TF1 human erythroleukemic cells. The ED50 for this effect is typically 0.5-3 ng/mL. (QC Test) Immobilized Human IL-13, No Tag at 1 μg/ml (100 μl/well) on the plate. Dose response curve for Human IL-13Ra2, His Tag with the EC50 of 3.6 ng/ml determined by ELISA. (QC Test) Loaded Human IL-13Ra2, His Tag on Anti-His-Biosensor can bind Human IL-13, No Tag with an affinity constant of 0.63 nM as determined in BLI assay (Gator® Prime). |
| 研究背景 | Interleukin-13 (IL-13) is a monomeric 17 kDa immunoregulatory cytokine that plays a key role in the pathogenesis of allergy, cancer, and tissue fibrosis. It is secreted by several helper T cell subsets, NK cells, mast cells, eosinophils, basophils, and visceral smooth muscle cells. Inhibits inflammatory cytokine production. Synergizes with IL2 in regulating interferon-gamma synthesis. May be critical in regulating inflammatory and immune responses. Positively regulates IL31RA expression in macrophages (By similarity). |

| 蛋白性状 | Lyophilized powder |
| 缓冲液 | Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
| 复溶方法 | Reconstitute the lyophilized protein in sterile deionized water. The product concentration should not be less than 100 μg/mL. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing. |
| 别名 | 白细胞介素, P600, interleukin 13, IL-13, ALRH |
| 内毒素 | < 0.1 EU/μg of the protein as determined by the LAL method. |
| 分子量 | 12.34 kDa (Predicted and reducing conditions) |

| 物理性状 | Lyophilized powder |
| 运输方式 | In general, Lyophilized powders are shipping with blue ice. Solutions are shipping with dry ice. |
| 存储 | Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots. |
