Purification of Extracellular Vesicles and Exosomes

EV purification

  • Scalable EV purification from biofluids, conditioned media, plants.

  • Method: Tangential flow filtration and size exclusion chromatography.

  • Separation of small (40 - 150 nm) and large (>150 nm) EVs.

  • Alternative methods: ultracentrifugation, immunoaffinity.

  • Validation: NTA (Zetaview, Particle Metrix), protein marker expression, total protein content.

Physical characterization of Extracellular Vesicles

EV purification

Characterization of the EV morphology:

  • Transmission Electron Microscopy (TEM).

  • Immuno Electron Microscopy.

Phenotyping of Extracellular Vesicles and Exosomes

EV purification

Characterization of EVs by the following methods:

  • ELISA high throughput marker screening, ideal for biomarker discovery.

  • Flow Cytometry: characterization by NanoFCM analyzer.

  • Fluorescence NTA: characterization by Zetaview analyzer (Particle Metrix).

EV-OMICS service

EV purification

Proteomic and trascriptomic analysis of EV markers:

  • Mass spectrometry: Sample preparation and Q Exactive Plus 2h nano-LC/MS/MS analysis with MaxQuant-based identification and quantitation.

  • RNA seq: Library preparation with Nextflex kit. Sequencing done by Illumina Nextseq 500
