GGT activity in exosomes isolated by differential centrifugation from serum of PC and BPH patients. Exosomes were isolated by differential centrifugation from serum (210 μL) of PC (n = 31) and BPH (n = 8) patients. GGT activity was determined by incubation with gGlu-HMRG at room temperature for 1 h and measurement of fluorescence intensity (Ex/Em 490/520 nm) using microplate reader. Patient groups were compared for serum PSA concentration (a), serum GGT activity (b) and serum exosomal GGT activity (c). *p < 0.05, compared with BPH patients
