FC - Quality tested

Application Notes:

Additional reported applications (for the relevant formats) include: in vitro blocking of NK cell cytotoxicity1,2.

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.25 µg per 106 cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

Mouse TRAIL transfected cells stained

Mouse TRAIL transfected cells stained with N2B2 PE


CD253 is a 40 kD TNF superfamily member known as TRAIL, Apo-2 ligand, and Apo-2L. TRAIL is expressed on a variety of cells, including IL-2 and IL-15 activated NK cells and activated T cells. However, it is undetectable on resting T and B cells. TRAIL has been reported to induce apoptosis in tumor and transformed cell lines by a caspase-dependent process. The N2B2 antibody has been reported to be useful for flow cytometric staining and blocking NK cell cytotoxicity in vitro.

Other Names: TNFSF10, TNF-related apoptosis inducing ligand, Apo-2 ligand, Apo-2L, CD253
Structure: TNF ligand superfamily member, approximately 40 kD
Distribution: Widespread, highest expression in spleen, lung, prostate; NK, monocytes, neutrophils, activated T cells
Function: Induces apoptosis in tumorigenic and transformed cell lines, involved in T cell mediated cytotoxicity
Ligand Receptor: TRAIL receptor DR5
