Application
Las características y beneficios generales observados del PMSF son:
- Inhibe las proteasas de serina como la tripsina y la quimiotripsina
- Inhibe también las proteasas de cisteína (reversible por tioles reducidos) y la acetilcolinesterasa de mamíferos
- No es tan eficaz ni tan tóxico como el DFP
- Concentración efectiva 0.1-1 mM
- Semivida = 1 h a pH 7,5
- fraccionamiento celular.
- como suplemento en la extracción de proteínas nucleares.
- como inhibidor de la colesterol esterasa (CE) y la pseudocolinesterasa (PCE).
- se utiliza para la recogida de sangre antes de la centrifugación para cuantificar los niveles plasmáticos de ANP.
