|Product name||Recombinant Human IL-18 Protein|
|Description||Recombinant Human IL-18 Protein is produced by E. coli expression system. The target protein is expressed with sequence (Tyr37-Asp193) of human IL-18 (Accession #NP_001553.1).|
|Bio-Activity||Measured by its ability to induce IFN-gamma secretion by KG-1 human acute myelogenous leukemia cells in the presence of TNF-alpha. The ED50 for this effect is typically 15-75 ng/ml.|
|Synonym||IGIF; IL-18; IL-1g; IL1F4|
|Expressed Host||E. coli|
|Purity||> 95% by SDS-PAGE.|
|Endotoxin||< 0.1 EU/μg of the protein by LAL method.|
|Formulation||Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.|
|Storage||Store the lyophilized protein at -20°C to -80 °C for long term.|
After reconstitution, the protein solution is stable at -20 °C for 3 months, at 2-8 °C for up to 1 week.
|Reconstitution||Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water.|
