Evaluation of urinary extracellular vesicles and microRNAs to diagnose urogenital tuberculosis

Figure 2 Urinary extracellular vesicles characterization using flow cytometry histogram depicting the expression of CD63 on the surface of urinary extracellular vesicles samples of the three study groups (n = 3/group). Samples urinary extracellular vesicle (uEV) 1, uEV2 and uEV3, captured on anti-human CD63 magnetic beads followed by anti-CD63 primary antibody and stained with detection antibody. Grey color on histogram represents CD63 positive-extracellular vesicle population. A: Unstained anti-human CD63 magnetic beads; B: Control; C: Urinary tract infections group; D: Urogenital tuberculosis group. FITC: Fluorescein isothiocyanate; UTI: Urinary tract infections; UGTB: Urogenital tuberculosis.
