Hardware adaptation to ~100nm EV's
The optical setup of the flow cytometer was modified to use the side scatter (SSC) information of the 405 nm laser (violet-SSC-A) instead of the 488 nm laser. The SSC was then calibrated using polystyrene beads of known diameter between 80 and 300 nm with a density of 1,05 g/cm_ and a refractive index of 1.59 nm (Cat 30080A, 30100A, 30200A and 30300A, Nanosphere serie 3000/ Thermofisher Scientific, Waltham, Massachusetts, USA). The forward scatter (FSC) and violet SSC-A were corrected on a logarithmic scale and the fluorescence channels were corrected on a logarithmic gain. The EV detection region was then set for events with size (by FSC) and complexity (by violet-SSC-A) characteristics of EVs. The SSC data generated by beads were fitted to nm according to Mie theory, using FCMPASS software (https://nano.ccr.cancer.gov/fcmpass/). Commercially available recombinant exosomes expressing green fluorescent protein (GFP) on their membrane surface (SAE0193, Merck) with a size distribution ranging from 30 to 200 nm (peak at 100-150 nm, measured by DLS) were used to validate the accuracy of the flow cytometer for the analysis of sEVs.

The optical setup of the flow cytometer was modified to use the side scatter (SSC) information of the 405 nm laser (violet-SSC-A) instead of the 488 nm laser. The SSC was then calibrated using polystyrene beads of known diameter between 80 and 300 nm with a density of 1,05 g/cm_ and a refractive index of 1.59 nm (Cat 30080A, 30100A, 30200A and 30300A, Nanosphere serie 3000/ Thermofisher Scientific, Waltham, Massachusetts, USA). The forward scatter (FSC) and violet SSC-A were corrected on a logarithmic scale and the fluorescence channels were corrected on a logarithmic gain. The EV detection region was then set for events with size (by FSC) and complexity (by violet-SSC-A) characteristics of EVs. The SSC data generated by beads were fitted to nm according to Mie theory, using FCMPASS software (https://nano.ccr.cancer.gov/fcmpass/). Commercially available recombinant exosomes expressing green fluorescent protein (GFP) on their membrane surface (SAE0193, Merck) with a size distribution ranging from 30 to 200 nm (peak at 100-150 nm, measured by DLS) were used to validate the accuracy of the flow cytometer for the analysis of sEVs.

Hardware adaptation to ~100nm EV's
The optical setup of the flow cytometer was modified to use the side scatter (SSC) information of the 405 nm laser (violet-SSC-A) instead of the 488 nm laser. The SSC was then calibrated using polystyrene beads of known diameter between 80 and 300 nm with a density of 1,05 g/cm_ and a refractive index of 1.59 nm (Cat 30080A, 30100A, 30200A and 30300A, Nanosphere serie 3000/ Thermofisher Scientific, Waltham, Massachusetts, USA). The forward scatter (FSC) and violet SSC-A were corrected on a logarithmic scale and the fluorescence channels were corrected on a logarithmic gain. The EV detection region was then set for events with size (by FSC) and complexity (by violet-SSC-A) characteristics of EVs. The SSC data generated by beads were fitted to nm according to Mie theory, using FCMPASS software (https://nano.ccr.cancer.gov/fcmpass/). Commercially available recombinant exosomes expressing green fluorescent protein (GFP) on their membrane surface (SAE0193, Merck) with a size distribution ranging from 30 to 200 nm (peak at 100-150 nm, measured by DLS) were used to validate the accuracy of the flow cytometer for the analysis of sEVs.
