|Cat. No. :
||The interleukin-18 receptor 1 (IL-18R1) is a cytokine receptor of the immunoglobulin superfamily. IL18R1 is also known as IL-18Rα, CDw218a (cluster of differentiation w218a), IL-1Rrp, and IL-1R family member. IL-18R1 specifically binds to interleukin 18 (IL18), and is essential for IL18 mediated signal transduction. IL-18Rα is expressed on Th1 cells, NK cell subset, neutrophils and IL-12-stimulated tonsillar B cells. By itself, IL-18Rα binds IL-18 with low affinity and when complexed with IL-18Rβ chain binds IL-18 with high affinity. The proinflammatory cytokine IL-18 and its receptor complex play an important role in the innate and autoimmune responses.
|Molecular Weight :
||The predicted molecular weight of Recombinant Human IL-18 Rα is Mr 63 kDa. However, the actual molecular weight as observed by migration on SDS Page is Mr 95-105 kDa.
|State Of Matter :
||>95% by SDS Page and analyzed by silver stain.
||<1.0 EU/µg as determined by the LAL method.
