PCR en tiempo real
El ensayo de PCR (abreviatura de reacción en cadena de la polimerasa) es un importante método de análisis de los alimentos y de diagnóstico médico.
Los ensayos de PCR en tiempo real duplican y analizan secuencias de ADN específicas. En el análisis alimentario, los ensayos de PCR se utilizan en muchas aplicaciones, como la detección de microorganismos patogénicos, la identificación de alérgenos, la detección de organismos genéticamente modificados (GMO) o la identificación de especies animales. Los ensayos de PCR ofrecen numerosas ventajas: Son muy específicos, sensibles, sólidos, rápidos y fiables. Además, se pueden automatizar.
- Seguro: método específico y validado
- Fiable: kits de ensayo con control de calidad
- Fácil de usar: preparación de muestras intuitiva y universal
- Efectivo: capacidad para cuantificación y procesamiento múltiple
- Versátil: numerosas áreas de aplicación
PCR en tiempo real explicada
En todos los análisis, el primer paso consiste en un muestreo representativo y una homogeneización. Tras la lisis de las células orgánicas del tejido de alimento, el ADN se preparará mediante diferentes kits de preparación de ADN y ARN específicos, ya sea para bacterias o para virus.
Los kits SureFood® PREP Basic y SureFood® Prep Advanced se utilizan para piensos y alimentos sólidos de origen animal o vegetal. En el caso de las bebidas, se utilizan kits de preparación de ADN específicos dependiendo de la matriz, mientras que la nueva gama de productos QuickGEN permite una manipulación sumamente sencilla.
El sistema modular de preparación del ADN y detección de ADN se puede utilizar de forma independiente. La amplificación del ADN de destino requiere, además de los kits apropiados, el uso de un termociclador adecuado con entre dos (FAM/HEX) y cuatro (FAM/HEX/ROX/Cy5) canales de detección.
Áreas de aplicación de PCR en el análisis de alimentos
Las alergias alimentarias pueden provocar reacciones alérgicas graves. Para proteger a los clientes, los productos alimentarios se deben analizar para determinar la presencia de sustancias alergénicas. Ofrecemos una amplia gama de kits de PCR para la detección de alérgenos como soja, avellana, cacahuete, gluten, almendra, apio, sésamo, mostaza, pescado o crustáceos. También ofrecemos ensayos múltiples para detección simultánea de varios alérgenos (cacahuete/avellana/nuez y apio/soja/mostaza).
La especificación de la especie es de interés especial: los productos cárnicos se pueden falsificar por medio de una declaración incorrecta (como en el escándalo de la carne de caballo). Otra de sus aplicaciones es la garantía del cumplimiento de prescripciones dietéticas de carácter religioso (halal, kosher). Nuestra gama de productos SureFood® Animal ID permite un análisis de mayor sensibilidad de muchos tipos de carne (cerdo, ternera, caballo, asno, pollo, pavo y otras especies). Con la línea de productos SureFood® Fish ID, ofrecemos una amplia gama de kits de PCR para la identificación de especies ícticas.
Durante la producción de bebidas, la detección de elementos que favorecen el deterioro es crucial. Con la línea de productos GEN-IAL®, ofrecemos una amplia gama de kits de cribado para la detección de organismos que causan el deterioro durante la producción de cerveza y vino, por ejemplo, Lactobacillus, Pediococcus, Megasphaera, Pectinatus, Dekkera bruxellensis o Oenococcus oeni. Los kits de ensayo se pueden utilizar tanto para control durante el proceso como para control del producto final.
En años recientes, la producción mundial de alimentos modificados genéticamente se ha incrementado paulatinamente. Desde que se estableció el etiquetado obligatorio de los productos alimentarios que contienen organismos modificados genéticamente (GMO), la demanda de métodos de ensayo de alta sensibilidad se ha incrementado. Nuestra gama de productos SureFood® GMO permite la detección cuantitativa y cualitativa de GMO, como maíz modificado genéticamente, arroz LibertyLink o soja Roundup Ready.
La detección de la contaminación microbiológica es uno de los principales campos de aplicación del PCR en análisis alimentario. Nuestra gama de productos SureFast® detecta una amplia gama de bacterias patogénicas (por ejemplo, Salmonella, Listeria, Legionella, E. coli, Staphylococcus aureus, Campylobacter), virus (por ejemplo, norovirus, hepatitis y gripe), así como levaduras y moho, en los alimentos.
