Rendimiento

Rendimiento superior
Las QIAcuity Master Mixes para la detección basada en EvaGreen utilizan las versiones más recientes de ADN polimerasa de alta calidad de QIAGEN. La combinación única de la patentada tecnología de tampón de eficacia comprobada de QIAGEN optimizada para microfluidos de nanoplacas, junto con el nuevo QuantiNova DNA Polymerase permite obtener resultados uniformes en lo que respecta a sensibilidad, reproducibilidad y eficacia.

Detección basada en colorante con EvaGreen
La mezcla maestra especial del QIAcuity EG PCR Kit permite la amplificación y cuantificación exactas de blanco de ADN de doble cadena. Incluye un colorante de referencia optimizado necesario para el análisis de dPCR y el recuento de divisiones analizables en las Nanoplates. Además, EvaGreen proporciona una señal de fluorescencia más elevada que SYBR Green en las mismas concentraciones y ofrece máxima amplificación, eficiencia, especificidad y sensibilidad en dPCR.

Estabilidad en la reacción de hasta 100 horas
Las mezclas para PCR QIAcuity pueden almacenarse a una temperatura de 30 °C durante un máximo de 100 horas sin que se altere el rendimiento de las reacciones posteriores. La excelente estabilidad, incluso tras un almacenamiento prolongado a temperatura ambiente sin el uso de ningún agente refrigerante hace que el QIAcuity EG PCR Kit sea ideal para la configuración de reacciones de alto rendimiento y la manipulación de pilas de placas.

Principio

El QIAcuity EG PCR Kit proporciona análisis de ADNc o ADNg con máxima especificidad gracias a su novedoso mecanismo de inicio en caliente mediado por anticuerpos. A bajas temperaturas, el QuantiNova DNA Polymerase se mantiene en un estado inactivo por acción del anticuerpo QuantiNova Antibody y un nuevo aditivo, QuantiNova Guard, que estabiliza el complejo. De esta manera, se mejora la astringencia del inicio en caliente y previene la extensión de oligonucleótidos alineados de manera no específica y de dímeros de oligonucleótidos. A los 2 minutos de haber alcanzado una temperatura de 95 °C, el QuantiNova Antibody y el QuantiNova Guard se desnaturalizan y se activa la QuantiNova DNA Polymerase, lo que permite la amplificación por PCR.

El principio de la reacción de dPCR en las nanoplacas se describe aquí.

Procedimiento

Al igual que en los experimentos de qPCR, la preparación de las muestras incluye la transferencia de mezcla maestra, sondas y cebadores a una nanoplaca de 96 o 24 pocillos, seguida de la adición de las muestras. El sistema integra funciones de división en partes, termociclado y obtención de imágenes en un solo instrumento completamente automatizado que permite a los usuarios obtener los resultados de las muestras en menos de 2 horas. Es posible realizar un análisis en el paquete de software, que proporciona la concentración en copias por microlitro de la secuencia de blancos y también para el control de calidad como muestras positivas o NTC. Este análisis también se puede extender a ordenadores remotos dentro de la misma red de área local (LAN).

Aplicaciones

El QIAcuity EG PCR Kit, junto con el QIAcuity Digital PCR System y las QIAcuity Nanoplates, permiten el análisis cuantitativo de blancos de ADNc y ADNg para utilizarlas en aplicaciones, entre las que se incluyen:

  • Detección de mutaciones poco frecuentes
  • Análisis de variación en el número de copias
  • Análisis de expresión génica
  • Detección de microrganismos patógenos
  • Genotipado
  • Investigación sobre miARN

Preguntas frecuentes

Is it possible to change voltage set-up from 110V to 230V on the QIAcuity instruments?

This is not needed. The QIAcuity is equipped with a flexible power supply technology and operates within a range of 100–240V AC, 50/60 Hz, 1500 VA (max). 

FAQ-3761
Can I see error codes on the instrument touchscreen?

The instrument software GUI shows error codes including a description and information how to resolve the error. The instrument touchscreen shows an alarm icon in the upper right corner that turns red in case of an instrument failure. Accessing the System Status in the Tool tab allows users to clear errors. Rebooting of the instrument is required to complete the removal of the error.  Please do not skip this step. You may always contact QIAGEN Technical Services in case of any question. 

FAQ-3763
What is the scope of a regular maintenance of the QIAcuity?

The user manual contains instructions on how to perform a regular cleaning and decontamination, and how to replace air filters on the QIAcuity instruments. A regular maintenance reduces the dust in the instrument and therefore minimizes the presence of dust particles on the nanoplate, which might interfere with the plate analysis.

FAQ-3765
What is the impact of not applying the latest VPF? Can I reanalyze previously obtained results after installing the latest VPF?

If you had run a nanoplate for which the installed VPF misses the specific factor, the software will notify you. If you then analyze without the specific VPF, the impact depends on the variation of the partition volume of the new Nanoplate batch compared to the latest. Typically this variation is ±6–7% (approx. 5% CV over the entire plate). The analysis may be repeated after updating the VPF file. After installing the latest VPF and re-analysis of the run, a copy of the plate is generated in the QIAcuity Software Suite including the new results. 

FAQ-3769
Can I see on the QIAcuity Software Suite report file if the VPF (Volume Precision Factor) has been used or not?

Yes, the report includes a notification if the matching VPF was missing and, therefore, not applied to the analysis. If the matching VPF was applied there is no notification on the report. 

FAQ-3770
Is it necessary to reanalyze a plate with VPF (Volume Precision Factor) that was already processed using a QIAcuity instrument that was purchased in 2020?

If you had analyzed your nanoplates without VFP, the impact depends on the variation of the partition volume of the new nanoplate batch compared to the latest. The VPF reduces the CV from approximately 5% to 2%. We recommend to reanalyze results in case the data originated from different wells (e.g., copy number variations or gene expression data sets for which the reference sample was measured in a different well). Results obtained across different plates should also be r-analyzed. A reanalysis is not required for assay data that were analyzed within the same well (e.g., mutation rate determination using two channels within the same well).

FAQ-3771
Can I prepare a dPCR reaction directly in QIAcuity Nanoplate?

A standard PCR plate is required to set up dPCR reaction before transferring it to the nanoplate to ensure a proper mixing of the reaction mix before partitioning. 

FAQ-3774
Can I use a custom master mix instead of a QIAGEN master mix?

QIAGEN master mixes are optimized for nanoplate microfluidics and are recommended to be used with our dPCR system. They also include an optimized reference dye required for proper analysis.

FAQ-3777
How to prepare DNA prior to dPCR?

All DNA samples used in reaction mixes should show similar quality and quantity, which can easily be assessed using UV spectrophotometry. DNA samples with an average length of ≥20 kb (e.g., genomic DNA purified via spin column with silica membrane) should be fragmented by restriction digestion before partitioning. Enzymatic fragmentation of larger DNA ensures an even distribution of template throughout the QIAcuity Nanoplate, which in turn leads to an accurate and precise quantification.

FAQ-3778
What are the storage conditions and expiry date of QIAcuity consumables?

The QIAcuity Probe PCR Kit should be stored immediately upon receipt at –30 to –15°C in a constant-temperature freezer and protected from light. The QIAcuity Probe PCR master mix can also be stored protected from light at 2–8°C. Components are stable for 12 months, unless otherwise indicated on the label. 
The QIAcuity EG PCR Kit should be stored immediately upon receipt at –30 to –15°C in a constant-temperature freezer and protected from light. The QIAcuity EG PCR master mix can also be stored protected from light at 2–8°C. Components are stable for 6 months, unless otherwise indicated on the label. 
The QIAcuity Nanoplates does not have expiry date and are stable for at least 1 year when stored at RT. 

FAQ-3780
Can I use the QIAcuity Nanoplate in more than one runs?

The plate is designed for a single use run. For example, even if only 30 samples are loaded into the 96-well plate, a whole plate will be sealed by the roller. It can't be unsealed and used for another run. The QIAcuity Software won’t allow to set up a separate experiment for the same nanoplate to avoid that previously processed plates being not partitioned a second time.

FAQ-3781
Can I optimize a dPCR assay on the QIAcuity using gradient temperature?

An essential temperature gradient functionality was introduced with software version 2.5. When updating older software versions to 2.5, each QIAcuity instrument will offer the temperature gradient and may be used to find the best cycling temperature for new dPCR assays. When running a QIAcuity Four or a QIAcuity Eight, all plates may have their own temperature profile, including the option for a temperature gradient.

FAQ-3783
What is the VPF (Volume Precision Factor)?

The VPF provides a set of well-specific and molding form-specific factors used to specify the exact reaction volume of a nanoplate, thus increasing the concentration calculation of each well. 

FAQ-3784
When and how often do I need a new VPF (Volume Precision Factor)?

 In general, nanoplates provide partitions of fixed sizes that enable a very precise way of sample concentration calculation. If a new molding form is used for nanoplate manufacturing, potential variation of partition sizes can be addressed by applying the molding form-specific VPF. Thus, each time a new molding form is used, a new VPF is created and made available. Currently, the VPF is updated once every 3–6 months.

FAQ-3785
Is a standard curve needed in dPCR?

In dPCR we measure the absolute concentration of targets at endpoint reaction. Concentrations of unknowns can be determined based on dPCR results observed (number of negatives, number of positives, and partition volume analyzed).
