Description | Anti-4-1BB/CD137/TNFRSF9 Antibody-PE (1B772) is a PE-conjugated Rabbit antibody targeting 4-1BB/CD137/TNFRSF9. Anti-4-1BB/CD137/TNFRSF9 Antibody-PE (1B772) can be used in FCM. |
Ig Type | Monoclonal Rabbit IgG |
Clone | 1B772 |
Reactivity | Human |
Verified Activity | Flow cytometric analysis of Human CD137 expression on PHA-activated human whole blood lymphocytes. Cells were stained with PE-conjugated anti-Human CD137. The fluorescence histograms were derived from gated events with the forward and side light-scatter characteristics of viable lymphocytes. |

Research Background | CD137 (also known as 4-1BB) is a surface co-stimulatory glycoprotein originally described as present on activated T lymphocytes, which belongs to the tumor necrosis factor (TNF) receptor superfamily. It is expressed mainly on activated CD4+and CD8+T cells, and binds to a high-affinity ligand (4-1BBL) expressed on several antigen-presenting cells such as macrophages and activated B cells. Upon ligand binding, 4-1BB is associated with the tumor necrosis factor receptor–associated factors (TRAFs), the adaptor protein which mediates downstream signaling events including the activation of NF-kappaB and cytokine production. 4-1BB signaling either by binding to 4-1BBL or by antibody ligation delivers signals for T-cell activation and growth, as well as monocyte proliferation and B-cell survival, and plays an important role in the amplification of T cell-mediated immune responses. In addition, CD137 and CD137L are expressed in different human primary tumor tissues, suggesting that they may influence the progression of tumors. Crosslinking of CD137 on activated T cells has shown promise in enhancing anti-tumor immune responses in murine models, and agonistic anti-CD137 antibodies are currently being tested in phase I clinical trials. Soluble forms of CD137 (sCD137) are generated by differential splicing. sCD137 can bind to CD137 ligand to antagonize the costimulatory activities of the membrane-bound CD137 and reduce T cell proliferation and IL-2 secretion.Cancer ImmunotherapyCo-stimulatory Immune Checkpoint TargetsImmune CheckpointImmune Checkpoint Detection: AntibodiesImmune Checkpoint Detection: ELISA AntibodiesImmune Checkpoint ProteinsImmune Checkpoint TargetsImmunotherapyTargeted Therapy |
