Abstract
Un método de PCR múltiple que comprende: amplificar múltiples ácidos nucleicos diana usando pares de cebadores anidados específicos de diana que comprenden cebadores directo externo, directo interno, inverso interno e inverso externo para cada diana en una primera reacción de amplificación, en el que la concentración de cebadores anidados es de 100-1000 nM, y en el que al menos uno de dichos cebadores internos comprende nucleótidos adicionales para proporcionar una secuencia adicional que no es específica para los ácidos nucleicos diana, de modo que la amplificación del ácido nucleico diana con dicho cebador también incorporará en el amplicón resultante un sitio de unión para un cebador común que, a diferencia de un cebador específico de diana, puede usarse para amplificar adicionalmente amplicones de ácido nucleico diana no relacionados, produciendo de este modo al menos un amplicón de ácido nucleico que contiene al menos un sitio de unión a cebador común; separar el al menos un amplicón de ácido nucleico de al menos una parte de los cebadores de la primera amplificación; y amplificar el al menos un amplicón de ácido nucleico en una segunda reacción de amplificación usando al menos un cebador común que se une con el al menos un sitio de unión a cebador común.

Una mezcla de cebadores que contiene 10 pmol de cada uno de los cebadores Fo, Fi, Ri y Ro en la Tabla 2. Para esta amplificación, solamente se incluyó un molde diana, Campylobacter jejuni. El molde se diluyó a 10 pg/μl, 1 pg/μl, 0,1 pg/μl, 0,01 pg/μl y 0,001 pg/μl. Se usó un kit de PCR Qiagen Multiplex para preparar una muestra que contenía 44 μl de mezcla Multiplex, 5 μl de mezcla de cebadores y 1 μl de molde. Las condiciones de ciclación fueron las siguientes:
95 °C durante 15 minutos 94 °C durante 15 segundos 55 °C durante 15 segundos 72 °C durante 15 segundos Estos tres ciclos se repitieron, 2-20 veces (15 veces en total para este ejemplo) 94 °C durante 15 segundos 70 °C durante 15 segundos Estos dos ciclos se repitieron, 6 veces en total para este ejemplo. 72 °C durante 3 minutos Mantenimiento a 4 °C
Tras completar la primera amplificación como se ha descrito anteriormente, se añadieron muestras a columnas de Millipore con un punto de corte de peso molecular de 50 kd y se centrifugaron durante 11 minutos a 13 k RPM para retirar una parte sustancial de los cebadores (peso molecular generalmente por debajo de 30 kd), rescatando
