Description
| Product Name: | Human il 18 Recombinant Protein |
| Product Code: | RPPB0620 |
| Size: | 25µg |
| Species: | Human |
| Target: | il 18 |
| Synonyms: | IGIF, IL-1g, IL-18, IL1F4, MGC12320, IFN-gamma-inducing factor, Interleukin-1 gamma, IL-1 gamma, Iboctadekin. |
| Source: | Escherichia Coli |
| Physical Appearance: | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation: | Lyophilized from a concentrated (1mg/ml) solution in PBS and DTT. |
| Solubility: | It is recommended to reconstitute the lyophilized Interleukin 18 in sterile 18M?-cm H2O not less than 200µg/ml, which can then be further diluted to other aqueous solutions. |
| Stability: | Lyophilized Interleukin 18 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL18 should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles. |
| Purity: | Greater than 95.0% as determined by SDS-PAGE. |
| Biological Activity: | The ED50 is 1.5-9 ng/mL and is measured by Interleukin 18 ability to induce IFN-? secretion by KG?1 human acute myelogenous leukemia cells in the presence of TNF-alpha. |
IL-18 is a proinflammatory cytokine. This cytokine can induce the IFN-gamma production of T cells. The combination of this cytokine and IL12 has been shown to inhibit IL4 dependent IgE and IgG1 production, and enhance IgG2a production of B cells. IL-18 binding protein (IL18BP) can specifically interact with this cytokine, and thus negatively regulate its biological activity.
Interleukin-18 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 157 amino acids and having a molecular mass of 18.2 kDa. The IL-18 is purified by proprietary chromatographic techniques.
| UniProt Protein Function: | IL18: Augments natural killer cell activity in spleen cells and stimulates interferon gamma production in T-helper type I cells. Belongs to the IL-1 family. |
