- El nuevo proceso de Covaris permite la extracción precisa de ARN de grado NGS a partir de muestras de tejido FFPE  

WOBURN, Massachusetts, 16 de diciembre de 2014 /PRNewswire/ -- Covaris, Inc. ha introducido el truXTRAC FFPE RNA Kit. Esta reciente innovación de Covaris extrae ARN de alta calidad, adecuada para secuenciación de próxima generación (NGS), de muestras de tejido FFPE. La calidad de NGS se logra mediante el uso de la tecnología Adaptive Focused Acoustics® (AFA) patentada de Covaris combinada con un sistema reactivo optimizado. El método de extracción truXTRAC FFPE RNA utiliza la energía acústica centrada y altamente controlada para eliminar parafina de muestras Fixed-Formalin, Paraffin-Embedded (FFPE) sin el uso de disolventes orgánicos, permitiendo la rehidratación de tejido eficiente y rápida, la digestión del tejido, la inversión de enlace cruzado y la liberación de ácido nucleico.    

Como resultado de esta metodología avanzada, el truXTRAC FFPE RNA Kit ofrece rendimiento incrementado de ARN de alta calidad que está disponible para ensayos de biología molecular complejos. Por ejemplo, la amplificabilidad mejorada es un atributo clave para la construcción de biblioteca NGS eficiente y el método truXTRAC FFPE RNA resulta en medidas de secuenciación de más alta calidad y permite nuevas aplicaciones clínicas.   

El consejero delegado de Covaris, Jim Laugharn, comentó: "El análisis de transcriptoma se está convirtiendo en una herramienta rutinaria para evaluar la progresión de la enfermedad. Los laboratorios clínicos se basan en ARN extraído de FFPE a una tasa de rápido aumento pero la escasa calidad del ARN derivada de métodos de extracción tradicionales la hacen inapropiada para el uso clínico. El proceso de Covaris para extracción precisa de ARN está posicionado únicamente para ajustarse a los requisitos de sensibilidad y análisis de aplicaciones clínicas, especialmente para secuenciación de próxima generación".

Las muestras de tejido clínico a menudo están estabilizadas en bloques de FFPE para mantener la histología con los análisis bioquímicos como preocupación secundaria. La fijación de formaldehído extrema y deshidratación de tejido duro de las secciones de tejido preservadas de FFPE ha presentado previamente un reto técnico para la extracción de ARN precisa para uso en ARN-Seq con NGS. Además, el proceso creó tiempos de respuesta largos y flujos de trabajo complicados en un entorno de laboratorio clínico. El truXTRAC FFPE RNA Kit de Covaris avanza la tecnología de preparación de muestras y ofrece la metodología fiable, reproducible y rápida requerida por laboratorios clínicos.
