Abstract

Un método para detectar una molécula de ácido nucleico de interés en una muestra, en el que la molécula de ácido nucleico de interés es un microARN, que comprende las siguientes etapas: - proporcionar una sonda de ácido nucleico en solución; - hibridación de la molécula de ácido nucleico de interés a la sonda de ácido nucleico para obtener un híbrido de dicha molécula de ácido nucleico de interés y dicha sonda de ácido nucleico; - enlazar dicho híbrido a un anticuerpo capaz de enlazar específicamente a híbridos de ácido nucleico, en el que el anticuerpo está enlazado a una fase sólida; y - detectar el híbrido enlazado a anticuerpo, en el que el anticuerpo está enlazado a un antígeno competitivo antes del enlace de dicho primer híbrido y dicho híbrido es detectado por desplazamiento del antígeno competitivo, en el que el antígeno competitivo es un híbrido competitivo de ácidos nucleicos, portando dicho híbrido competitivo una unidad estructural marcadora.

Las placas de ELISA se prerecubrieron con un anticuerpo anti-ADN:ARN-Híbrido bajo condiciones estándar (5 µg/ml en solución salina regulada con fosfato (PBS)). Después del recubrimiento, las placas de ELISA se lavaron con una solución de lavado comercialmente disponible o con un regulador TRIS/ácido cítrico.
5 Los híbridos se diluyeron 1:100, 1:1.000, 1:10.000 y 1:100.000 en
-PBS,
-PBS con 1 µg/ml de BSA y 0,1 µg/ml de Tween 20,
-PBS con 0,5 µg/ml de BSA y 0,05 µg/ml de Tween 20, o
-PBS con 0,25 µg/ml de BSA y 0,025 µg/ml de Tween 20 respectivamente y se incubaron sobre placas ELISA
10 recubiertas durante 1 hora a 37 ºC. Después de la incubación, las placas se lavaron e incubaron con un conjugado de Estreptavidina POD comercialmente disponible. Las placas se lavaron y se añadió una solución de sustrato cromogénico (tetrametilbencidina) a las placas. El desarrollo del color se paró mediante la adición de una solución de parada de ácido sulfúrico y se leyó la densidad óptica (OD) a 450 nm. Los resultados para las diluciones 1:100.000 de los híbridos 1 a 12 se dan en la tabla 2, a continuación.
