Application Abreviews Notes
Functional Studies
Flow Cyt
  • Application notes
    Flow Cyt: Use at a concentration of 3 - 5 µg/ml.
    FuncS: Use at an assay dependent dilution.Soluble antibody blocks DR4 receptor against TRAIL-induced apoptosis. Plastic-immobilized antibody induces apoptosis in sensitive cells.
    Recommended dilution of antibody: 2-3 µg/ml in cultivation medium
    Final concentration of TRAIL: 20-200 ng/ml
    Application note: It is recommended to add the antibody 15 min before addition of TRAIL.

    ICC/IF: Use at an assay dependent dilution.
    IP: Use at an assay dependent dilution.

    Not tested in other applications.
    Optimal dilutions/concentrations should be determined by the end user.
  • Target

    • Function
      Receptor for the cytotoxic ligand TNFSF10/TRAIL. The adapter molecule FADD recruits caspase-8 to the activated receptor. The resulting death-inducing signaling complex (DISC) performs caspase-8 proteolytic activation which initiates the subsequent cascade of caspases (aspartate-specific cysteine proteases) mediating apoptosis. Promotes the activation of NF-kappa-B.
    • Tissue specificity
      Widely expressed. High levels are found in spleen, peripheral blood leukocytes, small intestine and thymus, but also in K562 erythroleukemia cells, MCF7 breast carcinoma cells and activated T-cells.
    • Sequence similarities
      Contains 1 death domain.
      Contains 3 TNFR-Cys repeats.

    Vielen Dank für Ihren Anruf.
    Ich habe nachgefragt ob und wie die Spezifität der folgenden Antikörper getestet wurde:
    Dieser Antikörper wurde nicht experimentell auf die Kreuzreaktion mit anderen Trail Rezeptoren getestet. Ich k...

    We can confirm that ab14738 is DR4 specific (at least as far as tested on transfectants). Please do not hesitate to contact us again if you need further information,

    The protocol I sent is correct- this is how the originator uses its antibody. However, I think the originators do not optimally titrate the antibody since they do not worry about the load (unlimited access of antibody), so you may find you will be able...

    Thank you for your enquiry. Here is the protocol recommended for induction experiments: The antibody (at a final concentration 100 ug/ml) is spread onto the surface of plastic dish just to cover it (layer about 1-2 mm; e.g. 50 ul into a well of 96-...
