In the presence of a cross-linking antibody, Mouse polyHistidine Monoclonal Antibody (10 µg/mL, Catalog # MAB050) and sub-optimal amounts of Mouse CD3 epsilon Monoclonal Antibody (Catalog # MAB484), Recombinant Mouse OX40 Ligand/TNFSF4 (Catalog # 1236-OX) stimulates IL‑2 secretion in mouse T cells in a dose-dependent manner (orange line), as measured by the Mouse IL‑2 Quantikine ELISA Kit (Catalog # M2000). Under these conditions, IL‑2 secretion elicited by Recombinant Mouse OX40 Ligand/TNFSF4 (30 ng/mL) is neutralized (green line) by increasing concentrations of Rat Anti-Mouse OX40 Ligand/TNFSF4 Monoclonal Antibody (Catalog # MAB1236). The ND50 is typically 0.01-0.05 µg/mL.
