Se desarrolló un método no radioisotópico no marcado para evaluar la actividad de la uracilo-ADN glicosilasa utilizando la espectrometría de masas MALDI-TOF para el análisis directo de productos que contienen sitios apurínicos/apirimidínicos. El ensayo demostró ser bastante simple, específico, rápido y fácil de usar para la medición de la GLICosilasa de ADN.
