ab243091 Anti-IL-18 antibody [EPR19954-188] was shown to specifically react with IL-18 in wild-type HeLa cells. Loss of signal was observed when knockout cell line ab265274 (knockout cell lysate ab256952) was used. Wild-type and IL-18 knockout samples were subjected to SDS-PAGE. ab243091 and Anti-alpha Tubulin antibody [EP1332Y] - Microtubule Marker (ab52866) were incubated overnight at 4°C at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

Target data

Pro-inflammatory cytokine primarily involved in epithelial barrier repair, polarized T-helper 1 (Th1) cell and natural killer (NK) cell immune responses (PubMed : 10653850). Upon binding to IL18R1 and IL18RAP, forms a signaling ternary complex which activates NF-kappa-B, triggering synthesis of inflammatory mediators (PubMed : 14528293, PubMed : 25500532, PubMed : 37993714). Synergizes with IL12/interleukin-12 to induce IFNG synthesis from T-helper 1 (Th1) cells and natural killer (NK) cells (PubMed : 10653850). Involved in transduction of inflammation downstream of pyroptosis : its mature form is specifically released in the extracellular milieu by passing through the gasdermin-D (GSDMD) pore (PubMed : 33883744).
