Aquí se describe una nueva técnica de proteómica cuantitativa para la identificación de complejos de proteínas en Saccharomyces cerevisiae. En este estudio, hemos utilizado el método de SILAC junto con la purificación de afinidad seguida de espectrometría de masas para identificar con una alta especificidad de la unión de compañeros de una proteína del RE, Scs2p.
