Mouse OX40 Ligand/TNFSF4 Antibody

• Species Reactivity
  Mouse
• Specificity
  Detects mouse OX40 Ligand/TNFSF4 in direct ELISAs and Western blots. In direct ELISAs, approximately 5% cross-reactivity with recombinant human OX40 Ligand is observed.
• Source
  Polyclonal Goat IgG
• Purification
  Antigen Affinity-purified
• Immunogen
  Mouse myeloma cell line NS0-derived recombinant mouse OX40 Ligand/TNFSF4
  Gln49-Leu198
  Accession # P43488
• Formulation
  Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
• Endotoxin Level
  <0.10 EU per 1 μg of the antibody by the LAL method.
• Label
  Unconjugated

• Western Blot
  0.1 µg/mL
  Recombinant Mouse OX40 Ligand/TNFSF4 (Catalog # 1236-OX)
• Immunocytochemistry
  5-15 µg/mL
  See below
• Neutralization
  Measured by its ability to neutralize OX40 Ligand/TNFSF4-induced IL‑2 secretion in mouse T cells. The Neutralization Dose (ND₅₀) is typically 0.2-0.6 µg/mL in the presence of 100 ng/mL Recombinant Mouse OX40 Ligand/TNFSF4, 10 µg/mL a cross-linking antibody, Mouse polyHistidine Monoclonal Antibody, and sub-optimal amounts of Mouse CD3 epsilon Monoclonal Antibody.

OX40 Ligand/TNFSF4 in Mouse Splenocytes. OX40 Ligand/TNFSF4 was detected in immersion fixed mouse splenocytes using Goat Anti-Mouse OX40 Ligand/TNFSF4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1236) at 15 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 (blue). Specific staining was localized to the plasma membrane and cytoplasm. View our protocol for Fluorescent ICC Staining of Non-adherent Cells.

IL‑2 Secretion Induced by OX40 Ligand/TNFSF4 and Neutralization by Mouse OX40 Ligand/TNFSF4 Antibody. 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 (100 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Mouse OX40 Ligand/TNFSF4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1236). The ND50 is typically 0.2-0.6 µg/mL.
