4-1BB Ligand (TNFSF9, CD137, CDw137, ILA, MGC2172, T-cell, 4-1BB homolog, T-cell antigen ILA, Tumor necrosis factor receptor superfamily member 9 precursor)

4-1BB, also known as CD137, is a type I transmembrane protein belonging to the TNF
receptor superfamily (TNFRSF9). It is expressed on T cells, NK cells, monocytes,
neutrophils, dendritic cells, and eosinophils. The ligand for 4-1BB, 4-1BBL, is a TNF
ligand superfamily member (TNFSF9) expressed on the surfaces of activated antigen
presenting cells and T and B lymphoma cell lines. 4-1BB transduces a T cell
costimulatory signal to promote survival, proliferation, cytokine production, and effector
functions. On dendritic cells, 4-1BB ligation enhances cytokine production and
upregulates expression of B7-1 and B7-2 costimulatory molecules.

Suitable for use in Flow Cytometry, ELISA, and Western Blot. Other applications not tested.

Flow Cytometry: 25ug/ml
