- Detection of Human OX40/TNFRSF4 by Western Blot. Western blot shows lysates of human T regulatory cells (Tregs) and human peripheral blood mononuclear cells (PBMCs) untreated (-) or treated (+) with 1 μg/mL PHA for 5 days. PVDF membrane was probed with 0.5 µg/mL of Sheep Anti-Human OX40/TNFRSF4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3388) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for OX40/TNFRSF4 at approximately 45 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

- OX40/TNFRSF4 in Human Tonsil. OX40/TNFRSF4 was detected in immersion fixed paraffin-embedded sections of human tonsil using Sheep Anti-Human OX40/TNFRSF4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3388) at 3 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Sheep IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC006). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to plasma membrane.

- Detection of OX40/TNFRSF4 in Human T Cells by Flow Cytometry. Human T cells were treated for 3-5 days with 1 μg/mL PHA then stained with Sheep Anti-Human OX40/ TNFRSF4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3388, filled histogram) or control antibody (Catalog # 5-001-A, open histogram), followed by NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # NL010).

- CXCL8/IL-8 Secretion Induced by OX40L/TNFSF4 and Neutralization by Human OX40/TNFRSF4 Antibody. Recombinant Human OX40L/TNFSF4 (Catalog # 1054-OX) stimulates CXCL8/IL-8 secretion in the HT1080 human fibrosarcoma cell line transfected with human OX40/TNFRSF4 in a dose-dependent manner (orange line), as measured by the Human CXCL8/IL-8 Quantikine ELISA Kit (Catalog # D8000C). CXCL8/Il-8 Secretion elicited by Recombinant Human OX40L/TNFSF4 (10 ng/mL) is neutralized (green line) by increasing concentrations of Sheep Anti-Human OX40/TNFRSF4 Polyclonal Antibody (Catalog # AF3388). The ND50 is typically 0.025-0.16 µg/mL.
