Description
FLIVO® (FLuorescence in vIVO) is a powerful method for assessing caspase activity in vivo. SR-FLIVO® poly caspase probes are non-cytotoxic, cell-permeant fluorescent inhibitors of caspases optimized for use in whole live animals. The SR-FLIVO® poly caspase inhibitor probe contains the preferred binding sequence for most caspases (Val-Ala-Asp or VAD). This preferred poly caspase tripeptide binding sequence is labeled with a sulforhodamine B (SR) dye and a fluoromethyl ketone (FMK) reactive entity.
