BD Pharmingen™
Tnfsf4; OX40 ligand; OX40L; TXGP1; Txgp1l; gp34; Ath-1; Ath1; CD134L
Rat (QC Testing)
Mouse BALB/c IgG1, κ
ACI-S1 rat T-cell lymphoma cell line
Flow cytometry (Routinely Tested)
0.5 mg/ml
Aqueous buffered solution containing ≤0.09% sodium azide.


We recommend, as a second-step, the biotinylated goat anti-mouse Ig polyclonal antibody (Cat. no. 553999), followed by Streptavidin-PE (Cat. no. 554061).


  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
  3. Sodium azide is a reversible inhibitor of oxidative metabolism; therefore, antibody preparations containing this preservative agent must not be used in cell cultures nor injected into animals. Sodium azide may be removed by washing stained cells or plate-bound antibody or dialyzing soluble antibody in sodium azide-free buffer. Since endotoxin may also affect the results of functional studies, we recommend the NA/LE (No Azide/Low Endotoxin) antibody format, if available, for in vitro and in vivo use.
  4. Please refer to for technical protocols.

The ATM-2 antibody reacts with rat OX-40 Ligand (OX-40L, CD252), a member of the TNF Ligand superfamily.  Although there is controversy regarding mouse OX-40L expression, OX-40L has been shown to be expressed on human dendritic cells  and mouse activated B lymphocytes.  Rat OX-40L interacts with OX-40 Antigen (CD134) found predominantly on activated T cells. The OX-40L-OX-40 interaction is reciprocally costimulatory in that both T cells and B cells are activated in cross-linking. Rat OX-40L mRNA has been detected in various HTLV-I-transformed T-cell lines: F344-S1, WKA-S1, and ACI-S1.  In addition, total rat spleen cells activated with 5 ng/ml PMA and 0.5 µg/ml ionomycin for two days showed OX-40L expression, as determined by flow cytometric analysis, with the ATM-2 mAb.  As observed in the mouse and human systems, rat OX-40L also costimulates IL-2 production and proliferation of anti- D3-activated rat T cells.  The ATM-2 mAb blocks the costimulatory activity of OX-40L on rat T- cell proliferation.

Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
