Product information "IL1RA, Recombinant, Human (IL-1RA, Interleukin Receptor 1RA, Interleukin-1 Receptor Antagonist Prote"
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 400kb 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 153aa and having a molecular mass of 17000D. The IL1RA is purified by proprietary chromatographic techniques. Recombinant protein corresponding to human IL-1RA expressed in E. coli. , 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-dependent inhibition of IL-1 stimulation of D10S cells was found to be 0.5ng/ml. Storage and Stability: Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
