FC - Quality tested

Application Notes:

Additional reported applications (for the relevant formats) include: in vitro blocking of 4-1BB-mediated T cell proliferation2.

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.

CDw137 is a 39 kD TNF-receptor superfamily member also known as 4-1BB, TNFRSF9, Ly-63, and ILA (Induced by Lymphocyte Activation). CDw137 is expressed as monomers, dimers, and tetramers on activated T and B cells. Interaction of CDw137 with its ligand, 4-1BBL (CDw137L), is important in T-B cell costimulation. The 17B5 antibody has been reported to block 4-1BBL costimulated T cell proliferation.
