Our Abpromise guarantee covers the use of ab2219 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
Functional Studies Use at an assay dependent concentration. The antibody 2E5 has high neutralizing activity for human TRAIL in biological assays.
Flow Cyt Use a concentration of 1 - 10 µg/ml.
Neutralising Use at an assay dependent concentration. The antibody 2E5 has high neutralizing activity for human TRAIL in biological assays.


  • FunctionCytokine that binds to TNFRSF10A/TRAILR1, TNFRSF10B/TRAILR2, TNFRSF10C/TRAILR3, TNFRSF10D/TRAILR4 and possibly also to TNFRSF11B/OPG. Induces apoptosis. Its activity may be modulated by binding to the decoy receptors TNFRSF10C/TRAILR3, TNFRSF10D/TRAILR4 and TNFRSF11B/OPG that cannot induce apoptosis.
  • Tissue specificityWidespread; most predominant in spleen, lung and prostate.
  • Sequence similaritiesBelongs to the tumor necrosis factor family.
  • Cellular localizationMembrane.

  • Apoptosis induced in JURKAT human T cell leukemia cell line by soluble recombinant human TRAIL is completely blocked by anti-human TRAIL (2E5).
    The neutralizing activity of the antibody 2E5 has been confirmed with various sources of soluble recombinant human TRAIL.
    A - medium
    B - recombinant TRAIL
    C - recombinant TRAIL + anti-human TRAIL (2E5; 0.06 µg/ml)
    D - recombinant TRAIL + anti-human TRAIL (2E5; 0.24 µg/ml)

Product Wall

This antibody was raised against soluble recombinant TRAIL /APO-2L (extracellular domain). It completely neutralizes apoptosis in cells induced by TRAIL (e.g. by soluble recombinant human TRAIL) that is why datasheet states functional application.

Thank you for contacting us.
I have attached the data for the Functional Studies done with ab2219. We will add these to the datasheet as well very soon.
Also, I wanted to send you the information about our 3 for 2 promotion for all proteins t...
