Figure 1. T-cell activation by professional APCs can lead to distinct immune checkpoint expression on CD8 + T cells . Splenocytes were prepared from the spleens of OT-1 mice and separated into T cells (CD8+) and B-cells (CD19+) using MACS. DC (CD11c+) were prepared from the spleens of Flt3 ligand-treated B6 mice. T cells were stimulated with a control peptide (No Stim), the SIINFEKL peptide alone (No APC), ... View More

Product Specific Information
Description: The 17B5 monoclonal antibody reacts with mouse CD137, also known as 4-1BB, a member of the TNFR superfamily. CD137 is expressed as monomers, dimers, and tetramers on the surface of activated T cells around day 4-6 after activation through the TCR complex. Interaction of CD137 with its ligand, 4-1BBL, is reported to deliver a costimulatory signal important in the T-APC interaction. Recent data suggests CD317 is expressed on Tregs and may play a role in their proliferation. The monoclonal antibody 17B5 has strong antagonistic effect in in vitro functional assays.
Applications Reported: This 17B5 antibody has been reported for use in flow cytometric analysis and functional assays.
Applications Tested: The 17B5 antibody has been tested by flow cytometric analysis of activated mouse splenocytes cultures. This can be used at less than or equal to 0.5 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
Storage and handling: Use in a sterile environment.
Filtration: 0.2 µm post-manufacturing filtered.
Purity: Greater than 90%, as determined by SDS-PAGE.
Endotoxin Level: Less than 0.001 ng/µg antibody, as determined by LAL assay.
Aggregation: Less than 10%, as determined by HPLC.
Target Information
CD137, also known as TNFRSF9 or 4-1BB, is an inducible costimulatory molecule expressed mainly on activated T cells. Its ligand, known as 4-1BBL, is expressed on activated macrophages, mature B cells, hematopoietic stem cells, and myeloid progenitor cells. CD137 signaling leads to maintaining the survival of activated T cells and CD8+ memory T cells, and clonal expansion of T cells, but also to suppressing myelopoiesis and dendritic cell development. Triggered CD137 induces a cytokine release profile regulating peripheral monocyte survival. Soluble forms of CD137 may provide negative control mechanism for some immune responses.
