Abstract

Abstract : A highly specific, fluorogenic probe detects human neutrophil elastase (hNE) in activated neutrophils and Neutrophil Extracellular Traps (NETs). Abstract : A highly sensitive optical probe for the detection of activated neutrophils and Neutrophil Extracellular Traps (NETs) is reported. It is based on a triple-quenched, super-silent tri-branched probe that generates >20 fold increase in fluorescence upon cleavage. The probe was highly specific for human neutrophil elastase, a protease that mediates a variety of inflammatory diseases, and detected NETosis and neutrophil activation in in vitro differentiated neutrophils and isolated human neutrophils.
