Recombinant Human IL1RN

• Description:

  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.

• Gene Name:

  IL1RN

• Gene Aliases:

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

• Gene ID:

  3557

• Accession Number:

  P18510

• Organism:

  Human

• Source:

  E. coli

• Concentration:

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

• Purity:

  >95% as determined by SDS-PAGE

• Solubility:

  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.

• Function:

  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

• Molecular Weight:

  17

• Shipping Conditions:

  Ambient Temperature

• Storage Conditions:

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

• Appearance:

  Lyophilized Powder

• Formulation:

  Lyophilized from a 0.2 μm filtered tris solution with sodium chloride (pH 7.5)

• CAS Number:

  9000-83-3
