EClass:
32160000
Endotoxin:
<0.06EU/µg protein (LAL test; Lonza).
Form (Short):
solid
Formulation:
Lyophilized from 0.2µm-filtered solution in PBS.
Handling Advice:
Avoid freeze/thaw cycles.Centrifuge lyophilized vial before opening and reconstitution.
Long Description:
Protein. The extracellular domain of human CD137 [4-1BB] (aa 19-184) is fused to the N-terminus of the Fc region of human IgG1. Source: CHO cells. Endotoxin content: <0.06EU/µg protein (LAL test; Lonza). Lyophilized from 0.2µm-filtered solution in PBS. Purity: >98% (SDS-PAGE). Human CD137 (4-1BB) is a costimulatory molecule of the tumor necrosis factor (TNF) receptor superfamily. The glycoprotein 4-1BB is expressed mainly on activated CD4+ and CD8+ T cells and binds to a high-affinity ligand (4-1BBL) expressed on several antigen-presenting cells such as macrophages and activated B cells. Upon ligand binding, 4-1BB is associated with the tumor receptor-associated factors (TRAF), the adaptor protein and mediates downstream signaling events including the activation of NF-kappaB and cytokine production. 4-1BB signaling either by binding to 4-1BBL or by antibody ligation delivers signals for T cell activation and growth as well as monocyte proliferation and B cell survival, and plays a important role in the amplification of T cell-mediated immune responses. In contrast, it can also enhance activation-induced T cell apoptosis when triggered by engagement of the TCR/CD3 complex. In addition, the 4-1BB/4-1BBL costimulatory pathway has been shown to augment secondary CTL responses to several viruses and increase antitumor immunity. 4-1BB is therefore a promising candidate for immunotherapy of human cancer.
