||The interleukin-1 receptor antagonist (IL-1RA) is a protein that in humans is encoded by the IL1RN gene. IL-1RA was initially called the IL-1 inhibitor and was discovered separately in 1984 by two independent laboratories. IL-1RA is an agent that binds non-productively to the cell surface interleukin-1 receptor (IL-1R), the same receptor that binds interleukin 1 (IL-1), preventing IL-1 from sending a signal to that cell.

||<0.1 EU per 1 μg of the protein by the LAL method.
||Measure by its ability to inhibit IL-1 alpha-dependent proliferation in D10.G4.1 cells. The ED50 for this effect is < 50 ng/mL.
||>98% as determined by SDS-PAGE. Ni-NTA chromatography
|Storage Buffer :
||The protein was lyophilized from a solution containing 1X PBS, pH 7.4.
||It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 100 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.
||Lyophilized protein should be stored at -20°C. Upon reconstitution, protein aliquots should be stored at -20°C or -80°C.
||Please use within one month after protein reconstitution.
