Human CD137 Ligand is a type II transmembrane protein constitutively expressed by monocytes, B cells neuroblastoma cells (1), and some activated T cells. The interaction of CD137 (4-1BB) and CD137L can supply a costimulatory signal to T cells through CD137. This costimulus seems to be more effective for CD8+ effector T cells than  for CD4+ helper T cells (3).  The interaction can also effect a reverse signal, inducing monocyte activation (2), or T cell inactivation and programmed death (4) through CD137L.

Isotype: Murine IgG2a kappa

Immunogen: Recombinant human CD137L

Specificity: Antibody ANC5D6 binds to an extracellular epiopte of human CD137L present on Raji and U-937 cells, and also binds to recombinant CD137L-muCD8 in EIA and Western Blot (6).

Functional Application: Antibody ANC5D6 does not block the interaction between CD137L and CD137.
