Abstract

En el presente documento se proporcionan métodos de procesamiento de un polipéptido o proteína para análisis, por ejemplo, análisis de mapeo de péptidos mediante espectrometría de masas. En realizaciones a modo de ejemplo, el método comprende incubar una muestra digerida a un pH levemente ácido y/o en presencia de un caótropo, en donde la muestra digerida se produce digiriendo un polipéptido con una proteasa para producir una muestra digerida que comprende al menos dos péptidos. En realizaciones a modo de ejemplo, el método comprende digerir el polipéptido con una proteasa que escinde en sentido C-terminal con respecto a triptófano para producir una muestra digerida que comprende al menos dos péptidos. En realizaciones a modo de ejemplo, el método comprende digerir el polipéptido con tripsina a una razón en peso de enzima:sustrato (E:S) de aproximadamente 1:1 a aproximadamente 1:15 para producir una muestra digerida que comprende al menos dos péptidos. En aspectos a modo de ejemplo, la muestra digerida comprende al menos uno o dos péptidos que comprenden, cada uno, una tirosina en el extremo C-terminal.
