What are the key physical parameters used in EV characterisation?

The key physical parameters include particle size, concentration, zeta potential, and morphology.

How is purity assessment performed for isolated EVs?

Purity assessment is performed by evaluating the ratio of EV-specific protein markers to contaminating non-EV proteins, often using techniques such as nanoparticle tracking analysis, western blotting, and protein quantification.

What localization assay is commonly used to validate EV biomarkers?

Immunofluorescence staining combined with confocal microscopy is commonly used to confirm the subcellular localization of protein markers in EVs.

Which protein markers serve as biomarkers for PsC-EVs?

Common tetraspanin markers such as CD63, CD81, and CD9 serve as biomarkers for PsC-EVs, along with psoriasis-associated inflammatory proteins like IL-1β and S100A8/A9.

What other biomarkers are relevant for PsC-EV diagnostic characterisation?

Other relevant biomarkers include nucleic acids such as microRNAs, lipids, and stress-related proteins like HSP70, which aid in distinguishing PsC-EVs from EVs of other origins.
