Mouse IL-18 R alpha /IL-1 R5 Antibody Summary

Species Reactivity
Detects mouse IL-18 R in direct ELISAs. In direct ELISAs, this antibody does not cross-react with recombinant mouse (rm) IL-1 RI, rmIL‑1 RII, rhIL‑1 R3, recombinant human (rh) IL-1 R4, rhIL-1 R5, recombinant rat IL-1 R6, rmIL-1 R7, rhIL-1 R8, rhIL-1 R9, or rmSIGIRR.
Monoclonal Rat IgG2A Clone # 112624
Protein A or G purified from hybridoma culture supernatant
Mouse myeloma cell line NS0-derived recombinant mouse IL‑18 R alpha
Accession # Q61098
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.
Endotoxin Level
<0.10 EU per 1 μg of the antibody by the LAL method.


Recommended Concentration
Western Blot
1 µg/mL
Recombinant Mouse IL‑18 R alpha /IL‑1 R5
Measured by its ability to neutralize IL‑18/IL‑1F4-induced IFN‑ gamma secretion in activated mouse T cells. The Neutralization Dose (ND50) is typically 0.2-0.8 µg/mL in the presence of 0.5 ng/mL Recombinant Mouse IL‑18/IL‑1F4 and 0.1 ng/mL Recombinant Mouse IL‑12.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

IFN‑ gamma Secretion Induced by IL‑18/IL‑1F4 and Neutraliza-tion by IL‑18 R alpha /IL‑1 R5 Antibody. In the presence of Recombinant Mouse IL-12 (0.1 ng/mL, Catalog # 419-ML), Recombinant Mouse IL-18/IL-1F4 stimulates IFN-gamma secretion in activated mouse T cells in a dose-dependent manner (orange line), as measured by the Mouse IFN-gamma Quantikine ELISA Kit (Catalog # MIF00). Under these conditions, IFN-gamma secretion elicited by Recombinant Mouse IL-18/IL-1F4 (0.5 ng/mL) is neutralized (green line) by increasing concentrations of Mouse IL-18 Ra/IL-1 R5 Monoclonal Antibody (Catalog # MAB12161). The ND50 is typically 0.2-0.8 µg/mL.
