Product Introduction
Bioactivity
Chemical Properties
Storage & Solubility Information
| Bioactivity | Measured by its ability to inhibit IL13-dependent proliferation of TF-1 human erythroleukemic cells. The ED50 for this effect is typically 5-30 ng/mL.  |
| Description | IL-13RA2 Protein, Human, Recombinant (His) is expressed in HEK293 mammalian cells with His tag. The predicted molecular weight is 38 kDa and the accession number is Q14627. |
| Species | Human |
| Expression System | HEK293 Cells |
| Tag | C-His |
| Accession Number | Q14627 |
| Construction | A DNA sequence encoding the extracellular domain of human IL13Rα2 (NP_000631.1) (Met1-Leu342) was expressed with the a polyhistidine tag at the C-terminus. Predicted N terminal: Asp 27 |
| Protein Purity | > 85 % as determined by SDS-PAGE  |
| Endotoxin | < 1.0 EU/μg of the protein as determined by the LAL method. |
| Formulation | Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS, pH 7.4. Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization. |
| Reconstitution | Reconstituted with sterile deionized water to 0.25 mg/mL. Reconstitution conditions may vary depending on the lot. |
| Stability & Storage | It is recommended to store recombinant proteins at -20°C to -80°C for future use. 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. |
| Shipping | In general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice. |
| Synonyms | interleukin 13 receptor, α2, interleukin 13 receptor, alpha 2, IL-13R, IL13BP, CT19, CD213A2 |
| Research Background |
| Molecular Weight | 38 kDa (predicted); 49.7 kDa (reducing condition, due to glycosylation) |
| Storage | Lyophilized powder: -20~-80°C for 1 year | Solution: -80°C for 6 months |
