Description :Recombinant Human IL1RN was expressed in E. coli cells.

Species :Human

Expression System:E.coli

Genbank Number :P18510

Storage, Stability and Shipping :The lyophilized protein is stable for at least one year from date of receipt at -70oC. Upon reconstitution, this cytokine can be stored in working aliquots at 2o - 8oC for one month, or at -20oC for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.

Applications :Cell Assay

Endotoxin Level :<1.0 EU/μg of recombinant protein as determined by the LAL method.

Molecular Weight :17.0 kDa

Gene Aliases :IRAP, ICIL-1RA, IL1 inhibitor, IL1F3, IL-1ra, IL-1RN Recombinant Human Interleukin-1 Receptor Antagonist (IL1RN) Description

Reconstitution Protocol :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.

Scientific Background :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.

Sample Cell Assay Data :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

Purity :Recombinant Human IL1RN resolved on a 15% SDS-PAGE gel under reducing conditions and stained with Coomassie Brilliant Blue G-250
