Performances

Des performances supérieures
Les mélanges principaux QIAcuity pour la dPCR à base de sonde d’hydrolyse font appel aux dernières versions d’ADN polymérase QIAGEN de haute qualité. La combinaison unique entre la nouvelle ADN polymérase QuantiNova et la technologie de tampon exclusive et éprouvée de QIAGEN, optimisée pour la microfluidique des nanoplaques, fournit des résultats très homogènes en termes de sensibilité, reproductibilité et efficacité.

Détection à base de sonde simplex à 5-plex grâce au QIAcuity Probe PCR Kit
Le mélange principal spécial inclus dans le QIAcuity Probe PCR Kit permet de quantifier avec exactitude jusqu’à 5 cibles présentant des abondances très différentes dans un puits de la nanoplaque QIAcuity. Cela permet d’économiser du temps et de l'argent et de réduire la quantité d’échantillon nécessaire. De plus, les données de PCR duplex ou multiplex obtenues sont comparables à celles obtenues dans une PCR simplex.

Jusqu’à 100 heures de stabilité des réactions
Les mélanges de PCR QIAcuity peuvent être stockés à 30 °C pendant 100 heures sans compromettre les performances des réactions subséquentes. Cette stabilité exceptionnelle, même après un stockage prolongé à température ambiante en l’absence d’agent refroidissant, rend le QIAcuity Probe PCR Kit idéal pour la configuration de réactions et la manipulation de piles de plaques haut débit.

Principe

Le QIAcuity Probe PCR Kit permet d’effectuer des analyses simplex ou multiplex d’ADNc ou d’ADNg avec la plus grande spécificité grâce à un nouveau mécanisme hot start médié par anticorps. Aux basses températures, l’ADN polymérase QuantiNova DNA est conservée dans un état inactif par l’anticorps QuantiNova et un nouvel additif, le protecteur QuantiNova qui stabilise le complexe. Cela améliore la rigueur du hot start et prévient l’élongation de dimères d’amorces et d’amorces hybridées de façon non spécifique. Dans les 2 minutes qui suivent l’augmentation de la température à 95 °C, l’anticorps QuantiNova et le protecteur QuantiNova sont dénaturés et l’ADN polymérase QuantiNova est activée, permettant l’amplification par PCR.

Vous trouverez ici une description du principe de la réaction de dPCR sur nanoplaque.

Procédure

Comme dans les expériences de qPCR, la préparation des échantillons comprend le transfert du mélange principal, des sondes et des amorces sur une nanoplaque de 96 ou 24 puits, suivi de l’addition des échantillons. Le système intègre le partitionnement, le thermocyclage et l’imagerie dans un seul instrument entièrement automatisé qui permet aux utilisateurs de passer de l’échantillon aux résultats en moins de 2 heures. Il est possible d’effectuer l’analyse à l’aide de la suite logicielle, qui donne la concentration de la séquence cible en copies par microlitre et permet le contrôle qualité pour les échantillons positifs ou NTC. Cette analyse peut également être effectuée sur des ordinateurs à distance au sein du même réseau local (Local Area Network, LAN).

Applications

Associé avec le QIAcuity Digital PCR System et les QIAcuity Nanoplates, le QIAcuity Probe PCR Kit permet de faire l'analyse quantitative des cibles d’ADNc et d'ADNg pour une utilisation dans les applications telles que :

  • La détection des mutations rares
  • L’analyse des variations du nombre de copies
  • L’analyse de l’expression génique
  • La détection des agents pathogènes
  • Le génotypage
  • La recherche sur les miARN
  • La thérapie génique et cellulaire
  • La quantification de l’ADN résiduel 
  • La surveillance des eaux usées

QIAcuity Software Suite
SOFTWARE (381MB)
Version 1.1.3
For Version 2
Version 4.0

The Volume Precision Factor (VPF) offers a unique feature to secure precision of concentration results obtained from a QIAcuity dPCR run. 
In general, Nanoplates provide partitions of fixed sizes that enable a very precise way of sample concentration calculation. Potential variation of partition sizes in Nanoplate batches, caused by different microstructure molding forms, can be addressed by applying the batch specific VPF. Furthermore, the VPF includes well-specific volume information and therefore further increases precision of concentration calculation in each well of the Nanoplates.

After downloading and updating the VPF file within the QIAcuity Software Suite, the VPF is applied automatically to the analysis of a corresponding Nanoplate batch. The VPF file includes information from all available microstructure molding forms and connected Nanoplate batches. It will be stored on the PC where the QIAcuity Software Suite is installed. 

Required QIAcuity Software Suite version: Version 1.2 or higher.

Version 2.1

 

Beside of usability improvements and bug fixes, the new features address GMP requirements by offering additional support for 21 CFR part 11 compliance, copy number variation (CNV) analysis, support of future Nanoplates, and improved 1D scatterplot views.

Application Notes (3)
The goal of this work was to compare performance of quantitative PCR (qPCR) and digital PCR (dPCR) in the quantification of gene expression and Wolbachia abundances in Nasonia parasitoid wasps.
This study tested a workflow for quantitation and qualification of AAV samples using a duplex assay on the QIAcuity dPCR instrument targeting both an insert (GFP) and the viral backbone (AAV2-ITR). With very low intra-assay and inter-assay CVs <6.5%, we demonstrate one of the main benefits of dPCR: reproducibility.
Here we provide an integrated rAAV genome titer method using the QIAcuity Digital PCR (dPCR) System with detailed parameters for high assay performance. Using this optimized method for pre-PCR handling of in-process rAAV samples, the results demonstrated that QIAcuity dPCR system generates the same level of accuracy and precision as the current gold standard ddPCR system but with much faster sample-to-result times (2 hours vs 7 hours) and higher overall throughput and scalability.

Limitations of conventional PCR and qPCR when dealing with difficult, low-volume samples and complex mixtures with high background of competitive molecules and inhibitors have posed frequent challenges for researchers and clinicians in their routine work. With the new generation of PCR technologies, digital PCR has opened doors for diverse applications, and researchers are learning to ask questions only digital PCR can answer. Join QIAGEN's webinar on how digital PCR can help take your research applications through and beyond those challenges.
This presentation will introduce dPCR, discuss its advantages, and outline how the approach might be used to improve measurement in areas like clinical diagnosis, alone or in conjunction with other methods.
In this expert webinar, Dr. Kubista will share with you the experience he and his team have gathered at the TATAA Biocenter, developing applications and providing services using digital PCR for nearly 12 years. They have experienced all the problems common to dPCR analytical workflows and developed robust standard operating procedures to minimize the risk of error and maximize robustness and repeatability, and developed various controls to test the performance and validate the methods. He will also discuss dPCR assay design and validation and then focus on strategies for copy number determination and rare mutation detection.
The QIAGEN digital PCR technology and its expanded capability will not only transform the portfolio of conventional qPCR applications but also provide a more rapid, accurate, and sensitive method for finding answers to difficult biological questions. 
As the digital PCR technology evolves and becomes more accessible and affordable, the transition from qPCR and adoption of dPCR will hopefully no longer remain a challenge. Experts share insights in an upcoming webinar about the fully integrated, rapid, and highly flexible digital PCR portfolio from QIAGEN.

FAQ

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 ID - 9207
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. 

3774
How can I get the latest VPF (Volume Precision Factor)?
The up-to-date VPF can be downloaded in the resource section of the QIAcuity product webpage. The VPF  is compatible with the QIAcuity Software Suite 1.2 and higher. The latest VPF file contains all factors for all existing nanoplate batches. If a nanoplate from a new nanoplate batch is run and the latest version of the VPF was not installed, the software will recognize this and will give a message to install the latest VPF file. Please note that Applying the VPF file cannot be reversed.
FAQ ID - 9206

3773
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). 

3761
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. 

3769
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.

3777
Does an incorrect handling of a plate might affect the results?
The QIAcuity reads emitted fluorescence from the bottom of the plate, which is covered with a foil. For best results, keep the foil clean and avoid damages such as scratches. Also, keep the barcode on the side of the plate clean and intact. Ensure that you wear gloves when working with a plate and do not apply force to it. For a safe handling of the plate, please  place the plate into a nanoplate tray.

3779
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).

3771
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).

3786
How can I upgrade the software on the instrument (CSW) and the QIAcuity Software Suite?
Both software are designed to be upgraded by users. The user manual includes instructions on how to perform the upgrades; instructions for the QIAcuity Suite Software upgrade can be found at page 38 and instructions for the CSW upgrade on page 67 (QIAcuity User Manual, 03/2021).

FAQ ID - 9205
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.

3782
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.

3778
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.

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.

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.

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.

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.

Can I use an empty nanoplate without seal to perform a dry run?

The QIAcuity instrument software does not allow to read and process a plate without seal. If you would like to perform a dry run please use sealed plate and set up this plate in the QIAcuity Software Suite.

Can I use the dPCR master mix in a qPCR cycler for optimization purposes?

dPCR master mix can be used in qPCR to optimize sample concentration and/or primer/probe concentration prior to assay transfer from qPCR to dPCR.

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.

How can I get the latest VPF (Volume Precision Factor)?

The up-to-date VPF can be downloaded in the resource section of the QIAcuity product webpage. The VPF  is compatible with the QIAcuity Software Suite 1.2 and higher. The latest VPF file contains all factors for all existing nanoplate batches. If a nanoplate from a new nanoplate batch is run and the latest version of the VPF was not installed, the software will recognize this and will give a message to install the latest VPF file. Please note that Applying the VPF file cannot be reversed.

Does an incorrect handling of a plate might affect the results?

The QIAcuity reads emitted fluorescence from the bottom of the plate, which is covered with a foil. For best results, keep the foil clean and avoid damages such as scratches. Also, keep the barcode on the side of the plate clean and intact. Ensure that you wear gloves when working with a plate and do not apply force to it. For a safe handling of the plate, please  place the plate into a nanoplate tray.

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 ID - 9208
Can I optimize a dPCR assay on the QIAcuity using gradient temperature?
QIAcuity does not support temperature gradient in PCR cycling profile. However, optimization of a dPCR assay can be done by qPCR on a gradient cycler using the dPCR master mix and then transferred from qPCR to dPCR.

How are results stored within the QIAcuity Software Suite?

Results are stored as part of the plates within the QIAcuity Software Suite. In version 1.1.2, plates can be exported to another file location, for example, an external HDD, and imported again if needed. From version 1.2 onwards, plates can also be archived automatically. To do so, an archive destination has to be defined. Additional information can be found in the user manual.
