Abstract

En esta invención se describe un método para la identificación y cuantificación de proteínas en mezclas complejas que comprende aislar selectivamente los péptidos de cada proteína que no contienen histidina ni arginina (péptidos NHNR), determinar las concentraciones relativas de una o varias proteínas en muestras diferentes a partir de la relación entre las áreas de los espectros teóricos estimados para los péptidos NHNR marcados con isótopos diferentes en cada muestra, siendo la determinación de la concentración relativa de las proteínas válida para cualquier tipo de marcaje isotópico de los péptidos NHNR. El método evade la separación y purificación de las proteínas presentes en mezclas complejas y el análisis de todos los péptidos provenientes de la digestión enzimática. El método descrito es aplicable a la identificación de proteínas con fines vacunales, terapéuticos y diagnóstico.
