Cuantifique el microARN de forma sencilla y precisa con el kit de ensayo de microARN Quant-iT, un kit de detección de microARN (miARN) que detecta el miARN incluso en presencia de contaminantes comunes como sales, nucleótidos libres, disolventes, detergentes y proteínas. El ensayo es altamente selectivo para microARN sobre ARNr o ARNm grande (> 1000 bp).

Aunque el reactivo de ensayo no selecciona exclusivamente el miARN, puede cuantificar reproduciblemente el miARN en muestras puras hasta niveles tan bajos como 0,5 ng siguiendo el protocolo suministrado, incluso en presencia de ARNm.

Las características del kit de ensayo de microARN Quant-iT incluyen:
• Detección sensible de tan solo 0,5 ng de miARN en un pocillo de microplaca.
• Rango dinámico central de 5 a 500 ng/ml.
• Lecturas precisas para concentraciones de muestras de 50 ng/ml a 100 µg/ml

El kit de ensayo de microARN Quant-iT proporciona reactivos de ensayo concentrados, tampón de dilución y patrones de miARN prediluidos. Basta con diluir el reactivo 1:200, cargar 200 µl en los pocillos de una microplaca, añadir 1-20 µl de muestra, mezclar y leer la fluorescencia. El ensayo se realiza a temperatura ambiente y la señal es estable durante aproximadamente tres horas. Dado que el ensayo tolera de 1 a 20 µl de muestra en un volumen de ensayo de 200 µl, se pueden obtener resultados precisos para las concentraciones iniciales de muestra desde 50 ng/ml hasta 100 µg/ml.
Para uso exclusivo en investigación. No apto para uso en procedimientos diagnósticos.

Preguntas frecuentes

Why am I getting negative fluorescence values with my Qubit Assays?

Negative fluorescence is a physical impossibility. It is an artifact from software autocorrecting for background signal. This means your reader is picking up and subtracting out background light at the cost of your data. Make sure to do a buffer-only control and assess the type of signal. You may need to switch to a different plate.

DNA technology based bio-responsive nanomaterials have been widely studied as promising tools for biomedical applications. Gold nanoparticles (AuNPs) and graphene oxide (GO) sheets are representative zero- and two-dimensional nanomaterials that have long been combined with DNA technology for point-of-care diagnostics. Herein, a cascade amplification system based on duplex-specific nuclease (DSN)-assisted ... More

DNA and RNA nucleases play a critical role in a growing number of cellular processes ranging from DNA repair to immune surveillance. Nevertheless, many nucleases have unknown or poorly characterized activities. Elucidating nuclease substrate specificities and co-factors can support a more definitive understanding of cellular mechanisms in physiology and disease. ... More

The quality of life for millions of people worldwide is affected by chronic pain. In addition to the effect of chronic pain on well-being, chronic pain has also been associated with poor health conditions and increased mortality. Due to its multifactorial origin, the classification of pain types remains challenging. MicroRNAs ... More
Multifunctional hybrid nanoparticles as magnetic delivery systems for siRNA targeting the HER2 gene in breast cancer cells.

Breast cancer is a major cause of death among women worldwide. Resistance to conventional therapies has been observed in HER2-positive breast cancer patients, indicating the need for more effective treatments. Small interfering RNA (siRNA) therapy is an attractive strategy against HER2-positive tumors, but its success depends largely on the efficient ... More

Screening for colorectal cancer (CRC) is effective in the population at average risk. The most extended strategy in organized programs involves the fecal immunochemical test, which is limited by low sensitivity for the detection of advanced adenomas (AAs). We aimed to identify microRNA (miRNA) signatures in fecal samples that identify ... More
