| 背景描述 | IL18BP, specifically binds to IL-18, suppressing its activity. IL18BP lacks a transmembrane domain and is prominently expressed in the heart, lung, placenta, and spleen. Additionally, IL18BP regulates the early TH1 cytokine response by reducing IFN-gamma production, moderating T-helper type 1 immune responses. |
| 别称 | Tadekinig-alfa, IL18BP |
| 蛋白编码 | O95998 |
| 分子量 | The protein has a calculated MW of 18.44 kDa. The protein migrates as 35 kDa under reducing condition (SDS-PAGE analysis). |
| 表达系统 | HEK293 cell |
| 纯度 | >95% as determined by SDS-PAGE. |
| 生物活性 | Testing in process |
| 内毒素检测 | <0.1 EU per 1 μg of the protein by the LAL method. |
| 蛋白序列 | A DNA sequence encoding Human IL-18BP Protein(#O95998) (Met1-Gly194) was expressed with polyhistidine tag at the C-terminus. |
| 蛋白标签 | His Tag (C-term) |
| 产品形式 | The protein was lyophilized from a 0.2 µm filtered solution containing 1X PBS, pH 7.4. If you have any concerns or special requirements, please confirm with us. |
| 产品应用 | Cell Culture |
1. Before opening, centrifuge at 3000 rpm for 5 mins.
2.Initial Reconstitution
· Reconstitute the Lyophilized Protein in sterile H₂O to a concentration of 100-200 μg/mL.
· Then, incubate it at room temperature for at least 20 mins to ensure sufficient dissolution.
Do Not Vortex! Vigorous shaking may impair the biological activity of the protein.
· Store at 2°C to 8°C for up to 1 week.
3.Extended Storage
· After the initial reconstitution, further dilute the reconstituted protein in a buffer containing a carrier protein or stabilizer (e.g., 0.1% BSA, 10% FBS, 5% HSA, or 5% trehalose solution). The final concentration is not less than 10 μg/ml.
· Prepare aliquots (≥20 μl).
· Store at -20°C or -80°C for 3 to 6 months.
Avoid repeated freeze-thaw cycles.
| 储存 | Lyophilized Protein: Store at -20°C for 1 year. Initial Reconstitution: Store at 2°C to 8°C for up to 1 week. Extended Storage: Store at -20°C or -80°C for 3 to 6 months with a carrier protein or stabilizer. |
