Automatically generated
Vengono descritte le procedure sperimentali per l'esecuzione di etichette covalenti a base di dietilpirrocarbonato con rilevamento spettrometrico di massa. Il dietilpirrocarbonato viene semplicemente miscelato con il complesso proteico o proteico di interesse, portando alla modifica di residui di amminoacidi accessibili al solvente. I residui modificati possono essere identificati dopo la digestione proteolitica e l'analisi della cromatografia liquida/spettrometria di massa.
