Fig. 6From: Quantitative proteomic analysis and functional characterization of Acanthamoeba castellanii exosome-like vesiclesDetection of aminopeptidase activity in EVs from Acanthamoeba castellanii. The aminopeptidase activity of EVs was detected by the hydrolysis of Leu-AMC and Arg-AMC compared with that of the PBS-treated control. The released fluorescence with an emission wavelength of 440 nm represents the corresponding aminopeptidase activityBack to article page
