| 反应种属 | Human |
| 应用 | Western Blot(0.1 µg/mL) |
| 目标/特异性 | Detects human OX40 Ligand/TNFSF4 in direct ELISAs and Western blots. In direct ELISAs, less than 5% cross-reactivity with recombinant mouse OX40 Ligand/TNFSF4 is observed. |
| 使用方法 | Western Blot: 0.1 µg/mL Neutralization: Measured by its ability to neutralize OX40 Ligand/TNFSF4-induced IL-8 secretion in the HT1080 human fibrosarcoma cell line transfected with human OX40. Muller, N. et al. (2008) FEBS Journal 275:2296. The Neutralization Dose (ND50) is typically 0.015-0.09 μg/mL in the presence of 10 ng/mL Recombinant Human OX40 Ligand/TNFSF4. |

| 背景 | OX40 Ligand (OX40L), also known as gp34, is a type II transmembrane glycoprotein belonging to the TNF superfamily. Human OX40L cDNA encodes a 183 amino acids (aa) polypeptide with an amino-terminal cytoplasmic domain (aa 1-23) and a carboxy-terminal extracellular domain (aa 51-183). It shares 46% aa sequence identity with the mouse counterpart. OX40L is expressed on the surface of activated B cells, T cells, dendritic cells, and endothelial cells. Similarly to other TNF superfamily members, membrane-bound OX40 Ligand exists as a homotrimer. OX40L binds to OX40 (CD134), a member of the TNF receptor superfamily that is expressed predominantly on activated CD4+ T cells. OX40 Ligand is one of the co-stimulatory molecules in the immune system that includes B7, CD40 Ligand, CD30 Ligand, CD27 Ligand, and 4-1BB Ligand. Because OX40 appears as a late activation-induced T cell surface antigen, it has been speculated that the major function of OX40-OX40L interaction is to transmit a late co-stimulatory signal to promote the survival and proliferation of activated CD4+ T cells and prolong the immune response. Engagement of OX40 on activated T cells in situ in tumors has been shown to augment immune responses and subsequent tumor regression. |

Cell Proliferation Induced by OX40 Ligand/TNFSF4 and Neutralization by Human OX40 Ligand/TNFSF4 Antibody. In the presence of a cross-linking antibody, Mouse polyHistidine Monoclonal Antibody (10 µg/mL, Catalog # MAB050) and PHA (0.2 µg/mL), Recombinant Human OX40 Ligand/TNFSF4 (Catalog # 1054-OX) stimulates proliferation in human peripheral blood mononuclear cells (PBMC) in a dose-dependent manner (orange line). Under these conditions, proliferation elicited by Recombinant Human OX40 Ligand/TNFSF4 (10 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human OX40 Ligand/TNFSF4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1054). The ND50 is typically 0.03‑0.12 µg/mL. |
