Detail Information

ProSense® 750 FAST is part of a family of activatable fluorescent imaging agents comprising a novel architecture termed F.A.S.T. (Fluorescent Activatable Sensor Technology) that confers an improved pharmacokinetic profile with earlier imaging time points. This architecture offers higher target specific signal with reduced background while also reducing the optimal imaging time after injection. 

ProSense 750 FAST is a protease-activatable, pan-cathepsin fluorescent in vivo imaging agent that is activated by key disease associated proteases such as Cathepsin B, L, S, K, V and D. ProSense 750 FAST is not cleaved by trypsin or plasmin. 

Cathepsins are produced by inflammatory and tumor cells. ProSense 750 FAST is optically silent in its un-activated state and becomes highly fluorescent following protease-mediated activation. ProSense 750 FAST has a half-life in plasma of 30 minutes. ProSense 750 FAST may be used to study disease onset and progression in animal models of oncology, inflammation and atherosclerosis.
