| Gene ID |
3557 |
| Accession | P18510 |
| Alternative Name | IRAP, ICIL-1RA, IL1 inhibitor, IL1F3, IL-1ra, IL-1RN<br/>Recombinant Human Interleukin-1 Receptor Antagonist (IL1RN) |
| Species | Human |
| Source | E. coli |
| Description | IL1RN is found in the conditioned medium of a variety of cells and is produced by macrophages, monocytes, and neutrophils. The soluble form of IL1RN has been shown to be produced by hepatocytes and to be regulated by pro-inflammatory cytokines. It may help in the treatment of sepsis, cachexia, rheumatoid arthritis, chronic myelogenous leukemia, asthma, psoriasis, and inflammatory bowel disease. |
| Accession | P18510 |
| Functions | The ED50 was determined by the ability to inhibit the IL-1 alpha mediated cell proliferation in a murine helper T cell line, for this effect, in the presence of 50 pg/mL of IL-1 alpha, is typically 20-60 ng/mL |
| Formulation | Lyophilized from a 0.2 ?m filtered tris solution with sodium chloride (pH 7.5) |
| Solubility | A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers. |
| Appearance | Lyophilized Powder |
| Molecular Weight | 17 |
| Purity | >95% as determined by SDS-PAGE |
| Concentration | < 1.0 EU/μg of recombinant protein as determined by the LAL method. |
| Shipping Condition | Ambient Temperature |
| Storage Condition | The lyophilized protein is stable for at least one year from date of receipt at -70?C. Upon reconstitution, this cytokine can be stored in working aliquots at 2? - 8?C for one month, or at -20?C for six months, with a carrier protein without detectable loss of activity.
Avoid repeated freeze/thaw cycles. |
