Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting,

Specificity / Sensitivity

TNFRSF9/4-1BB Antibody recognizes endogenous levels of total TNFRSF9/4-1BB protein.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gln128 of human TNFRSF9/4-1BB protein. Antibodies are purified by protein A and peptide affinity chromatography.

Western Blotting

Western Blotting

Western blot analysis of extracts from activated primary human CD8+ T cells and HDLM-2 cells using TNFRSF9/4-1BB Antibody.

Western Blotting

Western Blotting

Western blot analysis of extracts from COS-7 cells, mock transfected (-) or transfected with a construct expressing Myc-tagged full-length human TNFRSF9/4-1BB (hTNFRSF9/4-1BB-Myc; +), untreated (-) or treated (+) by PNGase F, using TNFRSF9/4-1BB Antibody (upper), Myc-Tag (9B11) Mouse mAb #2276 (middle), or β-Actin (D6A8) Rabbit mAb #8457 (lower).


TNFRSF9 is a member of the tumor necrosis factor receptor superfamily (1, 2). It is also called 4-1BB or CD137 (1, 2). TNFRSF9/4-1BB is expressed in activated CD4+ and CD8+ T cells, natural killer cells and dendritic cells (2-5) . The ligand TNFSF9/4-1BBL on antigen presenting cells binds to TNFRSF9/4-1BB and costimulates the activation of T cells (5). The binding of agonistic antibodies to TNFRSF9/4-1BB also leads to costimulation for T cell activation (5). Studies have shown the effectiveness of targeting TNFRSF9/4-1BB by its agonistic antibodies in cancer immunotherapy (6).
