Analysis of CD9 and GAPDH expression in EVs from plasma of cancer patients. CD9-EV levels on EVs were measured by TRiFIC and GAPDH transcripts in EV-RNA were determined by digital PCR. The boxplots shows for 8 patients of cohort 1 in a) CD9 levels per mL plasma and c) GAPDH copies/mL plasma measured in plasma collected in different tubes (EDTA, BCT and CellSave) and processed at two time points (1 h and 24 h). For the second cohort of 8 patients and 15 Healthy Blood Donor (HBDs) are boxplots presented in b) CD9 levels per mL plasma and d) GAPDH copies/mL plasma both collected in EDTA tubes and processed within 24 h (< 24 h) from the blood draw. CD9 measurements were performed in duplicate
