Human CD137 (4-1BB) is expressed on activated T cells within 24-48 hours of activation (3). CD137 is a type I membrane protein and a member of the tumor necrosis factor receptor superfamily (1,2). CD137 appears to be important for T cell proliferation and survival (4) and induces monocyte activation (5).
Isotype: Murine IgG1 kappa
Immunogen: Ectodomain of recombinant human 4-1BB fusion protein
Specificity: Antibody 4B4-1 recognizes an extracellular epiopte of the human CD137 molecule of about 35 kd on activated T cells (3).
Functional Application: Antibody 4B4-1 blocks binding of CD137 huIg to Raji cells. Immobilized mAb has been shown to induce TNF a production by monocytes(6) and IFNg production by NK cells(7).
