Abstract

La presente invención describe un método para detectar la presencia de patógenos, incluido el SARS-CoV-2, en una muestra. El método usa proteínas efectoras de CRISPR junto con un ARN guía y una molécula indicadora. Las moléculas de ARN de la muestra primero se extraen opcionalmente y se transcriben inversamente, seguidas de la amplificación, de tal manera que cuando el ARN guía se hibrida con un fragmento de nucleótido objetivo en el ADN amplificado, la proteína efectora de CRISPR escinde la molécula indicadora, lo que da como resultado una señal detectable.
