W19242A_LEAF_CD218a_Antibody_022324
Recombinant human IL-18 (Cat. No. 592104) (black circles) stimulates the production of human IFN-γ (Cat. No. 430104) in human KG-1 cells. LEAF™ purified anti-human CD218a (IL-18Rα) (clone W19242A) (purple squares) inhibits this effect of recombinant human IL-18 (Cat. No. 592104) at 8 ng/mL in KG-1 cells in a dose-dependent manner, whereas the GoInVivo™ purified rat IgG2a, κ isotype control (Cat. No. 400562) (gray triangles) does not have this effect. ND50 range: 1-7 ng/mL.

Description

IL-18 is essential for both innate and adaptive immunity. The IL-18 receptor is composed of an α and a β subunit that form a high affinity heterodimer for IL-18. IL-18R1, also known as IL-18Rα chain and CD218a, is a type I transmembrane protein. It is expressed on NK cells, neutrophils, endothelial cells, and subsets of T and B cells. The expression of IL-18R1 and IL-18RAcP (IL-18Rβ) on lymphocytes are upregulated upon IL-12 stimulation. IL-23 and IL-18 synergistically enhance IL-18R1 expression on NK-like T cells. Upon IL-18 engagement, the intracellular TIR domain of IL-18R1 and IL-18RAcP recruits adaptor proteins, MyD88, and in turn recruits IRAK and TRAF6, activating NF-κB and MAPK pathways, which upregulates production of various inflammatory cytokines. The interaction of IL-18 and IL-18 receptor has been reported to be implicated in promotion of Th1 cytokine production and atherogenesis. IL-37 also binds to IL-18R1, but recruits IL-1R8 (SIGIRR) to activate anti-inflammatory responses.

Related FAQs

Do you guarantee that your antibodies are totally pathogen free?

BioLegend does not test for pathogens in-house aside from the GoInVivo™ product line. However, upon request, this can be tested on a custom basis with an outside, independent laboratory.

Does BioLegend test each Ultra-LEAF™ antibody by functional assay?

No, BioLegend does not test Ultra-LEAF™ antibodies by functional assays unless otherwise indicated. Due to the possible complexities and variations of uses of biofunctional antibodies in different assays and because of the large product portfolio, BioLegend does not currently perform functional assays as a routine QC for the antibodies. However, we do provide references in which the antibodies were used for functional assays and we do perform QC to verify the specificity and quality of the antibody based on our strict specification criteria.

Does BioLegend test each Ultra-LEAF™ antibody for potential pathogens?

No, BioLegend does not test for pathogens in-house unless otherwise indicated.  However, we can recommend an outside vendor to perform this testing as needed.

Have you tested this Ultra-LEAF™ antibody for in vivo or in vitro applications?

We don't test our antibodies for in vivo or in vitro applications unless otherwise indicated. Depending on the product, the TDS may describe literature supporting usage of a particular product for bioassay. It may be best to further consult the literature to find clone specific information.
