Osocimab

• CAT Number: I041550
• CAS Number: 2056878-75-0
• Purity: ≥95%

Osocimab (BAY 1213790), an anti-FXIa antibody (Ki=2.4 nM; EC50=0.2 nM). FXI inhibition may reduce the risk of thrombosis. Osocimab inhibits thrombin generation, and prolongs activated partial thromboplastin time. Osocimab exhibits anticoagulant effects[1].
Osocimab (1.4 nM-1 μM; 30 min) inhibits thrombin generation, and also inhibits FXIa-mediated activation of FIX (FIX conversion) (IC50=16 nM) and FXIa mediated substrate cleavage (IC50=1.2 nM) in human plasma[1].
Osocimab (22.05 mg/mL) inhibits intrinsic pathway-mediated activation of the coagulation cascade[1].
