Abstract

La presente invención se refiere a la detección de una secuencia de ácido nucleico objetivo mediante en ensayo PTOCE (Escisión y Extensión del PTO). La presente invención detecta una secuencia de ácido nucleico objetivo en la cual el PTO (Oligonucleótido de Sondeo y Marcaje) hibridado con la secuencia de ácido nucleico objetivo se escinde para liberar un fragmento y el fragmento se hibrida con el CTO (Oligonucleótido de Captura y Modelado) para formar un duplo extendido, seguido por la detección de la presencia del duplo extendido. El duplo extendido provee señales (generación, incremento, extinción o disminución de señales) de etiquetas que indican la presencia del duplo extendido y tiene un valor Tm ajustable, las cuales son bien adoptables para la detección de la presencia de la secuencia de ácido nucleico objetivo.
