- 08:26Conclusion
De beskrevne protokoller indeholder en guide til at visualisere og kvantificere aktiviteten af neutrofile proteaser i menneskeligt spyt. Anvendelsen af en sådan analyse spænder fra evaluering af antiinflammatoriske behandlinger til biomarkørvalidering, lægemiddelscreening og store kliniske kohorteundersøgelser.
