Product Name:Human IL 1RA Recombinant Protein
Product Code:RPPB0465
Size:100µg
Species:Human
Target:IL 1RA
Synonyms:IRAP, IL1F3, IL1RA, IL-1ra3, ICIL-1RA, IL1RN, IL1 inhibitor, IL-1ra, MGC10430.
Source:Escherichia Coli
Physical Appearance:Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation:Lyophilized protein with no additives.
Solubility:It is recommended to reconstitute the lyophilized Interleukin-1 ra in sterile 18M-cm H2O not less than 100�g/ml, which can then be further diluted to other aqueous solutions.
Stability:Lyophilized Interleukin 1ra although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL-1ra should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.
Purity:Greater than 98.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.
Amino Acid Sequence:The sequence of the first five N-terminal amino acids was determined and was found to be Met-Arg-Pro-Ser-Gly
Biological Activity:The ED50 as determined by the dose-dependant inhibition of IL-1 stimulation of D10S cells was found to be 0.5 ng/ml corresponding to a Specific Activity of 2,000,000IU/mg.

Interleukin-1 ra is a member of the interleukin 1 cytokine family. This protein inhibits the activities of interleukin 1, alpha (IL1A) and interleukin 1, beta (IL1B), and modulates a variety of interleukin 1 related immune and inflammatory responses. This gene and five other closely related cytokine genes form a gene cluster spanning approximately 400 kb on chromosome 2. A polymorphism of this gene is reported to be associated with increased risk of osteoporotic fractures and gastric cancer. Four alternatively spliced transcript variants encoding distinct isoforms have been reported.

IL1ra Human Recombinant produced in E.Coli is a non-glycosylated, N-terminal methionyl form of the human naturally-occurring polypeptide chain containing 153 amino acids and having a molecular mass of 17000 Dalton. The IL1ra is purified by proprietary chromatographic techniques.

UniProt Protein Function:IL1RN: Inhibits the activity of interleukin-1 by binding to receptor IL1R1 and preventing its association with the coreceptor IL1RAP for signaling. Has no interleukin-1 like activity. Binds functional interleukin-1 receptor IL1R1 with greater affinity than decoy receptor IL1R2; however, the physiological relevance of the latter association is unsure. The intracellular form of IL1RN is predominantly expressed in epithelial cells. 4 isoforms of the human protein are produced by alternative splicing.
