Product Specific Information
- For immunohistochemistry (PFA-fixed): incubate antibody for 30 minutes at room temperature.
- Staining of formalin-fixed tissues requires heating in 10 mM Tris Buffer with 1 mM EDTA, pH 9.0, for 45 minutes at 95°C, followed by cooling at room temperature for 20 minutes.
Target Information
CD137 (also known as TNFRSF9 or 4-1BB) is an inducible costimulatory molecule expressed mainly on activated T cells. Its ligand, 4-1BBL, is expressed on activated macrophages, mature B cells, hematopoietic stem cells, and myeloid progenitor cells.
CD137 signaling supports survival and clonal expansion of activated and memory T cells, while modulating myelopoiesis and dendritic cell development. Triggered CD137 induces cytokine release affecting peripheral monocyte survival. Soluble CD137 may act as a negative regulator of immune responses.
