| Description |
Tilvestamab (BGB149) is a humanized anti-AXL antibody that blocks AXL-mediated cell signaling. Tilvestamab significantly inhibits Gas6-induced AXL activation in 786-0-Luc RCC cells and inhibits downstream AKT phosphorylation. Tilvestamab can be used in cancer research, particularly in AXL overexpressing renal cell carcinomas[1].

| In Vitro |
Tilvestamab (250 µM; 1 h) inhibits AXL phosphorylation in 786-0 cells[1]. Cell Viability Assay[1] Cell Line: 786-0-Luc cells (Gas6- induced; Gas6 is a well characterized AXL ligand) Concentration: 250 µM Incubation Time: 1 h (pre-treat) Result: Drastically inhibited Gas6- induced AXL phosphorylation and decreased the level of pAKT.

| In Vivo |
Tilvestamab (30 mg/kg; i.p.; twice a week) suppresses tumor growth by inhibiting AXL in orthotopic RCC model[1]. Animal Model: Female BALB/c athymic nude mice (8-week-old; orthotopic RCC model)[1]. Dosage: 30 mg/kg Administration: Intraperitoneal injection; twice a week Result: Significantly inhibited RCC growth down to about 1/3 of the volume.
