Nous présentons ici un protocole visant à purifier les exosomes de plasma et de sérum réduit co purification de protéines sanguines non-exosomal. Le protocole optimisé inclut l’ultrafiltration, le traitement de la protéase et chromatographie d’exclusion. Améliorée de purification des exosomes des analyses en aval avantages, y compris la quantification plus précise des vésicules et la caractérisation de la protéomique.
