Interleukin-1 Receptor Type 2 (IL-1RII) is a non-signaling receptor for IL1A, IL1B and IL1RN and reduces IL1B activities. It serves as a decoy receptor by competitive binding to IL1B and preventing its binding to IL1R1. It also modulates cellular response through non-signaling association with IL1RAP after binding to IL1B. IL1R2 (membrane and secreted forms) preferentially binds IL1B and poorly IL1A and IL1RN. The secreted IL1R2 recruits secreted IL1RAP with high affinity; this complex formation may be the dominant mechanism for neutralization of IL1B by secreted/soluble receptors.

Human, Primate
Recombinant Protein
This whole rabbit serum was prepared by repeated immunizations with recombinant human IL-1R type II.
This antiserum is directed against the extracellular domain of the human IL-1R type II, but precipitates the intact receptor expressed on human cells.  In general, this antibody also detects primate IL-1RII.  The antibody does not recognize human IL-1, IL-1Ra or IL-1R type I.  In ELISA formats and other immunoreactive assays, this antibody will detect the extracellular domain of the IL-1R type II (also called soluble IL-1R type II) found in human body fluids, particularly in the circulation, urine and supernatants of cells and synovial fluid.

Application Details

This antiserum against Human IL-1 Receptor Type II (IL-1RII) has been tested by western blot and is suitable for use in ELISA, radioimmunoassays and immunoprecipitation.  Reactivity in other immunoassays is unknown.  IL-1RII has been termed p68 or CD121 in some laboratories.  IL-1RII has been shown to bind IL-1, IL-1a and IL-1b.
