El perfilado proteómico de las proteínas nitratodeadas por tirosina ha sido una técnica desafiante debido a la baja abundancia de la modificación de 3-nitrotirosina. Aquí describimos un enfoque novedoso para el enriquecimiento y perfilado de nitropéptidos mediante el uso de Angiotensin II como modelo. Este método se puede extender para otros sistemas in vitro o in vivo.
