Protocol for separation of fungal extracellular vesicles using ultracentrifugation from solid medium cultures

Year: 2024

Type: article

Abstract: Extracellular vesicles (EVs) have been identified in diverse fungi, including human pathogens. In this protocol, we present two techniques for isolating and analyzing fungal EVs. The first is for high-throughput screening, and the second is for yielding concentrated samples suitable for centrifugation-based density gradients. We describe steps for analytical assays such as nano-flow cytometry and nanoparticle tracking analysis to measure EV dimensions and concentration. EV suspensions can serve diverse assays, including electron microscopy, compositional determination, and cell-to-cell communication assays. For complete details on the use and execution of this protocol, please refer to Rizzo et al.,1 Rizzo et al.,2 Reis et al.,3 and Reis et al.4
