Specificity / Sensitivity
4-1BB/CD137/TNFRSF9 (D2Z4Y) Rabbit Monoclonal Antibody recognizes endogenous levels of total 4-1BB/CD137/TNFRSF9 protein.
Species Reactivity: Human
Source / Purification
Monoclonal antibody is produced by immunizing animals with a recombinant protein specific to the extracellular domain of human 4-1BB/CD137/TNFRSF9 protein.
Background
TNFRSF9 is a member of the tumor necrosis factor receptor superfamily (1,2). It is also called 4-1BB or CD137 (1, 2). 4-1BB/CD137/TNFRSF9 is expressed in activated CD4+ and CD8+ T cells, natural killer cells and dendritic cells (2-5). The ligand 4-1BBL/CD137L/TNFSF9 on antigen presenting cells binds to 4-1BB/CD137/TNFRSF9 and costimulates the activation of T cells (5). The binding of agonistic antibodies to 4-1BB/CD137/TNFRSF9 also leads to costimulation for T cell activation (5). Studies have shown the effectiveness of targeting 4-1BB/CD137/TNFRSF9 by its agonistic antibodies in cancer immunotherapy (6).
