| Product Details | |
|---|---|
| Synonyms | Interleukin-27 |
| Product Type | Protein |
| Properties | |
| Source/Host | CHO cells |
| Sequence |
The human IL-27 complex composed of the Ebi3 subunit (aa 21-229) and the p28 subunit (aa 26-243) is fused through a polypeptide linker to the Fc portion of a mutant human IgG1. |
| Crossreactivity | Human |
| Biological Activity |
Bioactivity was measured in a cell proliferation assay using anti-CD3 activated human peripheral mononuclear cells. |
| Purity | ≥98% (SDS-PAGE) |
| Endotoxin Content | <0.06EU/μg protein (LAL test; Lonza). |
| Reconstitution |
Reconstitute in 50µl sterile water. Add 1X PBS to the desired protein concentration. |
| Formulation | Lyophilized from 0.2μm-filtered solution in PBS. |
| Protein Negative Control | |
| Other Product Data |
Non-lytic: Acts as a long lasting fusion protein which only binds to the receptor. Mutations to the complement (C1q) and FcgR I binding sites of the IgGs Fc fragment render the fusion proteins incapable of antibody directed cytotoxicity (ADCC) and complement directed cytotoxicity (CDC). |

Description
Interleukin-27 (IL-27) is a heterodimeric group 2 receptor ligand molecule that belongs to the IL-6/IL-12 family of long type I cytokines. It is composed of EBI3 (EBV-induced gene 3), a 34 kDa glycoprotein that is related to the p40 subunit of IL-12 and IL-23, and p28, the cloned 28 kDa glycoprotein that is related to the p35 chain of IL-12. IL-27 is expressed by monocytes, endothelial cells and dendritic cells. IL-27 binds to and signals through a heterodimeric receptor complex composed of WSX1 (TCCR) and gp130. Evidence suggests IL-27 interacts only with WSX-1. IL-27 has both anti- and proinflammatory properties. As an antiinflammatory, IL-27 seems to induce a general negative feedback program that limits T and NK-T cell activity. At the onset of infection, IL-27 induces an IL-12 receptor on naïe CD4+ T cells, making them susceptible to subsequent IL-12 activity (and possible Th1 development). Notably, IL-12 family cytokines are both induced and inhibited by bacterial products. Microbes promote IL-27 secretion through TLR4, and also block IL-27 production via C5a induction.
