Recombinant Mouse IL-1ra/IL-1F3/IL1RN Protein Summary

Description
A single non-glycosylated polypeptide chain containing 152 amino acids corresponding to IL-1ra/IL-1F3/IL1RN Source: E. coli

Uniprot ID: Q542W1

Amino Acid Sequence: RPSGKRPCKM QAFRIWDTNQ KTFYLRNNQL IAGYLQGPNI KLEEKIDMVP IDLHSVFLGI HGGKLCLSCA KSGDDIKLQL EEVNITDLSK NKEEDKRFTF IRSEKGPTTS FESAACPGWF LCTTLEADRP VSLTNTPEEP LIVTKFYFQE DQ

This lyophilized preparation is stable at 2-8 degrees C, but should be kept at -20 degrees C for long term storage, preferably desiccated. Upon reconstitution, the preparation is most stable at -20 to -80 degrees C, and can be stored for one week at 2-8 degrees C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 degrees C to -80 degrees C. Avoid repeated freeze/thaw cycles.
Details of Functionality
IL-1ra/IL-1F3/IL1RN protein is fully biologically active when compared to standard. The ED50 as determined by inhibiting IL-1alpha- dependent proliferation of murine D10S cells is less than 50 ng/ml, corresponding to a specific activity of > 2.0 x 104 IU/mg in the presence of 50 pg/ml rHuIL-1alpha.

Background

IL-1RA was initially called the IL-1 inhibitor which is encoded by the IL1RN gene and it is a member of the interleukin 1 cytokine family. IL-1RA is secreted by various types of cells including immune cells, epithelial cells, and adipocytes. IL-RA has functions of inhibiting the activity of interleukin-1 by binding to receptor IL1R1 and preventing its association with the coreceptor IL1RAP for signaling. IL-1RA is also used in the treatment of rheumatoid arthritis, an autoimmune disease in which IL- 1 plays a key role. The murine IL-1RA is a single non-glycosylated polypeptide chain containing 152 amino acids and it has been shown to block the inflammatory responses induced by IL-1 both in vitro and in vivo. The protein shows 26 % amino acid homology to IL-1beta and 19 % homology to IL-1alpha. It also shares 90 % a.a. sequence identity with rat IL-1RA.
