Human IL18 (Y37-D193)
Accession # NP_001230140.1 |
| Predicted molecular mass | 18.2 kDa |
| Appearance | White powder, Colorless clear liquid after reconstitution |
| Purity | ≥95%, by SDS-PAGE (under conditions, visualized by Coomassie staining) |
| Endotoxin | ≤0.01EU/μg by the LAL method |

| Reconstitution | It is recommended to redissolve in sterile deionized water. |
| Shipping | Wet ice (seasonal) |
| Storage&Stability
|
36 months at -20°C to -80°C in lyophilized state
6 months at -20°C to -80°C under sterile conditions after reconstitution 7-10 days at 2°C to 8°C under sterile conditions after reconstitution Use a manual defrost freezer and avoid repeated freeze-thaw cycles. |
