- Western Blot Shows Human IL-18/IL-1F4 Specificity by Using Knockout Cell Line. Western blot shows lysates of HeLa human cervical epithelial carcinoma parental cell line and IL-18/IL-1F4 knockout HeLa cell line (KO). PVDF membrane was probed with 1 µg/mL of Goat Anti-Human/Rhesus Macaque IL-18/IL-1F4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2548) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for IL-18/IL-1F4 at approximately 25 kDa (as indicated) in the parental HeLa cell line, but is not detectable in knockout HeLa cell line. GAPDH (Catalog # AF5718) is shown as a loading control. This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

- IL-18/IL-1F4 in Human PBMCs. IL-18/IL-1F4 was detected in immersion fixed human peripheral blood mononuclear cells (PBMCs) using Goat Anti-Human/Rhesus Macaque IL-18/IL-1F4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2548) at 5 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (green). Specific staining was localized to cytoplasm.

- IFN-gamma Secretion Induced by IL-18/IL-1F4 and Neutralization by Primate IL-18/IL-1F4 Antibody. In the presence of Recombinant Human TNF-alpha (20 ng/mL, Catalog # 210-TA), Recombinant Rhesus Macaque IL-18/IL-1F4 (Catalog # 2548-RM) stimulates IFN-gamma secretion in the KG-1 human acute myelogenous leukemia cell line in a dose-dependent manner (orange line), as measured by the Human IFN-gamma Quantikine ELISA Kit (Catalog # DIF50). Under these conditions, IFN-gamma secretion elicited by Recombinant Rhesus Macaque IL-18/IL-1F4 (10 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human/Rhesus Macaque IL-18/IL-1F4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2548). The ND50 is typically 0.4-1.2 µg/mL.
