Les protocoles décrits ci-dessus fournissent un guide pour visualiser et quantifier l’activité des protéases neutrophiles dans les expectorations humaines. Les applications de cette analyse vont de l’évaluation des traitements anti-inflammatoires à la validation des biomarqueurs, au dépistage des médicaments et aux études cliniques de grandes cohortes.
