CD137, a member of the tumor necrosis factor (TNF) receptor family, is a type 1 transmembrane protein, expressed on surfaces of leukocytes and non-immune cells. CD137 is only expressed on the cell surface after T cell activation. When T cells are activated by Antigen Presenting Cells (APCs), CD137 becomes embedded in CD4+ and CD8+ T cells. CD137 is a costimulatory molecule functioning to stimulate T cell proliferation, dendritic cell maturation, and promotion of B cell antibody secretion. CD137 is also involved in cancer having been found upregulated in cancerous cell lines. CD137/ligand stimulation has been found to lead to stronger anti-tumor responses due to cytotoxic T cell activation and is being examined as a possible anticancer therapy.

Flow cytometric analysis of EL4 (Mouse lymphoma T lymphocyte, left) / CTLL-2 (Mouse T lymphocyte, right) cells labelling CD137 antibody at 1/500 dilution (0.1 μg)/ (Red) compared with a Rabbit monoclonal IgG (Black) isotype control and an unlabelled control (cells without incubation with primary antibody and secondary antibody) (Blue). Goat Anti - Rabbit IgG Alexa Fluor® 488 was used as the secondary antibody.
Negative control: EL4

IHC shows positive staining in paraffin-embedded mouse spleen. Anti-CD137 antibody was used at 1/250 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.
IHC shows positive staining in paraffin-embedded mouse thymus. Anti-CD137 antibody was used at 1/250 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.
IHC shows positive staining in paraffin-embedded mouse colon. Anti-CD137 antibody was used at 1/250 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.
ICC shows positive staining in CTLL-2 cells (top panel) and negative staining in EL4 cells (below panel). Anti-CD137 antibody was used at 1/500 dilution (Green) and incubated overnight at 4°C. Goat polyclonal Antibody to Rabbit IgG - H&L (Alexa Fluor® 488) was used as secondary antibody at 1/1000 dilution. The cells were fixed with 100% ice-cold methanol and permeabilized with 0.1% PBS-Triton X-100. Nuclei were counterstained with DAPI (Blue). Counterstain with tubulin (Red).
