Species: Mouse Expressing host: E. coli Description: Recombinant Mouse IL-1Ra/IL-1F3/IL-1RN Protein is produced byE. coliexpression system. The target protein is expressed with sequence (Arg27-Gln178) of mouse IL-1Ra/IL-1F3/IL-1RN (Accession #P25085) fused with an initial Met at the N-terminus. Tag: No tag Purity: > 95% by SDS-PAGE. Endotoxin: preparation: Lyophilized from a 0.22 m filtered solution of PBS, pH 7.4. Storage Store the lyophilized protein at -20C to -80 C for long term.
After reconstitution, the protein solution is stable at -20 C for 3 months, at 2-8 C for up to 1 week.Unopened freeze-dried powder,Store at -20 to -80 °C for twelve months
Redissolution: Centrifuge the tube before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid votex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.Redissolution:Store at -20 to -80 °C,avoid repeated freeze thaw cycles
Background Information : Interleukin-1 receptor antagonist protein (Il1rn), also known as IL-1ra, IRAP or IL1 inhibitor, is a member of theinterleukin 1 cytokine family. This protein inhibits the activities of interleukin 1 alpha (IL1A) and interleukin 1beta (IL1B), and modulates a variety of interleukin 1 related immune and inflammatory responses. The mouseIl1rn gene encodes a 178 amino acids (aa) protein with a 26 aa signal peptide. Mouse Il1rn protein shares 26%and 19% identity with its homologues IL-1 beta and IL-1 alpha, respectively. Il1rn can Inhibits the activity ofinterleukin-1 by binding to receptor IL1R1 and preventing its association with the coreceptor IL1RAP forsignaling, but has no interleukin-1 like activity. Recently, an recombinant human Il1rn protein is used in thetreatment of rheumatoid arthritis, an autoimmune disease in which IL-1 plays a key role. GeneID 16181 Swiss Prot P25085 Alias: IL-1ra; F630041P17Rik;IL1RNMedChemExpress (MCE) recombinant proteins include: cytokines, enzymes, growth factors, hormones, receptors, transcription factors, antibody fragments, etc. They are often essential for supporting cell growth, stimulating cell signaling pathways, triggering or inhibiting cell differentiation; and are useful tools for elucidating protein structure and function, understanding disease onset and progression, and validating pharmaceutical targets. At MedChemExpress (MCE), we strive to provide products with only the highest quality. Protein identity, purity and biological activity are assured by our robust quality control and assurance procedures.
