Overview

Catalog No.	HC336036
Description	Anti-Human 4-1BB/TNFRSF9/CD137 Reference Antibody (CTX-471, RUO) (HC336036) is a human monoclonal antibody detecting 4-1BB Ligand/TNFSF9.
Species reactivity	Human
Applications	ELISA, Bioactivity: FCM, Functional assay, Research in vivo
Host species	Human
Clonality	Monoclonal
Isotype	IgG
Clone ID	CTX-471
Biological activity	CTX-471 (5-500 nM) has bind affinity for recombinant human, cynomolgus macaque CD137 and mouse CD137 with K d values of 50 nM, 61 nM and 748 nM, respectively [1]. CTX-471 binds to a unique epitope on CD137 [1]. CTX-471 (0.1-100 nM; 1, 10 ug/mL; 3 days) increases IFN-y production by human T cells in an Fcy receptor-dependent (FcyR-dependent) manner in vitro [1]. CTX-471 (i.p.; 150 ug) exhibits curative monotherapy activity in various syngeneic tumor models and shows a unique ability to cure mice of very large tumors. CTX-471 (i.v.; 10-80 mg/kg; on days 0, 7, 14, and 21) is well tolerated, with no signs of hepatic toxicity in high doses.

Background	Tumor necrosis factor receptor superfamily member 9 (CD137/4-1BB) is a ~27 kDa protein. Receptor for TNFSF9/4-1BBL. Conveys a signal that enhances CD8(+) T-cell survival, cytotoxicity, and mitochondrial activity, thereby promoting immunity against viruses and tumors (Probable).
