Titration of EVs derived from glioblastoma cells. EV Neuro median signal intensities for increasing total numbers of NCH82 EVs (a) and LN18 EVs (b) as determined by NTA particle count. The number of 2.8 × 10⁷ particles (turquoise) represents the input of 120 µl of pre-cleared cell culture supernatant (10,000 × g) without prior EV enrichment. Other particle inputs (blue and red) were achieved by EV enrichment via dUC. Bars reflect marker profiles of one experiment each
