Principle

In nur 3 einfachen Schritten erhalten Sie in ca. 2 Stunden das gewünschte dPCR-Ergebnis: pipettieren und laden, Experiment durchführen, Ergebnisse auswerten.

Das Prinzip der dPCR-Reaktion in den Nanoplatten finden Sie hier beschrieben.

Procedure

Genau wie bei qPCR-Experimenten umfasst die Probenvorbereitung den Transfer von Master-Mix, Sonden und Primern in eine 96- oder 24-Well-Nanoplatte, gefolgt von der Zugabe der Proben. Das System integriert Partitionierung, Thermocycling und Bildgebung in nur einem Vollautomaten, der den Benutzer in weniger als 2 Stunden von der Probe zum Ergebnis führt. Mit der Software Suite lassen sich Auswertungen durchführen, die die Konzentration der Zielsequenz in Kopien pro Mikroliter sowie Qualitätskontrollen wie positive Proben und NTC liefern. Diese Auswertung kann auch auf Remote-Computer innerhalb desselben lokalen Netzwerks (LAN) ausgedehnt werden.

Applications

Zusammen mit den QIAcuity Nanoplates und QIAcuity PCR Kits ermöglichen die QIAcuity Geräte digitale PCR-Anwendungen, darunter:

Nachweis seltener Mutationen
Auswertung der Variation der Kopienzahl
Genexpressionsanalyse
Pathogennachweis
Genotypisierung
miRNA-Forschung

Software

Die mit dem Gerät gelieferte und auf einem separaten Computer installierte QIAcuity Software Suite steuert ein oder mehrere QIAcuity Geräte, die entweder direkt mit einem Gerät verbunden sind oder ein vorhandenes lokales Netzwerk (LAN) nutzen. Mit der QIAcuity Software Suite können digitale PCR-Experimente, Proben und Reaktionsmischungen definiert, Nanoplatten zugeordnet und auf das QIAcuity Gerät übertragen werden. Nach dem Gerätelauf können die Daten analysiert, Berichte erstellt und die Daten zur externen Auswertung exportiert werden. Die Software bietet multiple Template-Funktionen, um sich wiederholende Plattenlayouts und Plattenlaufparameter leicht aufrufen zu können und so Ihre Erfahrung mit der digitalen PCR weiter zu optimieren.

Bei Integration in ein lokales Netzwerk dient der Computer, auf dem die QIAcuity Software Suite installiert ist, als Server, auf den andere Computer als Clients über das LAN zugreifen können. So können mehrere Benutzer von anderen Räumen oder Büros aus auf die Software zugreifen und Daten über einen Standardbrowser analysieren, ohne dass die Software auf mehreren Computern installiert werden muss oder der Zugriff und Austausch von Daten über Internetverbindungen benötigt wird.

Here, we present a highly efficient, high-throughput workflow that combines two technologies, cellenONE and QIAcuity Digital PCR, to accurately analyze miRNAs in well-defined individual cells and populations of cells.

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 present a workflow that combines two technologies, cellenONE and QIAcuity Digital PCR, which accelerate and streamline high-throughput analyses of target copy numbers in cultured cells. The workflow starts with detecting and sorting defined populations of cells as well as individual cells using cellenONE, followed by multiplexing dPCR on the QIAcuity platform. Copy number variations of target regions are then analyzed using the QIAcuity Software Suite, providing an intuitive and fast interpretation of results.

With the cellenONE-QIAcuity workflow, we achieved high-throughput absolute quantification of low-abundance targets at the single-cell level. cellenONE’s single-cell isolation platform enabled real-time and 100% accurate single-cell isolation without compromising viability and transcript expression. This allowed us to use the exact number of intact cells for RT-dPCR reactions. Moreover, the elimination of the RNA purification step significantly reduced hands-on time, and QIAcuity’s probe-based chemistry allowed the multiplexing of up to five targets in a one-step RT-dPCR format with no or minimal optimization.

Here we report the use of saliva samples in combination with dPCR as a suitable alternative to screen for individuals infected with SARS-CoV-2.

The QIAgility instrument is a liquid handler designed for automating PCR setup. For compatibility with the QIAcuity, we developed an adapter to secure up to two nanoplates onto the deck of the QIAgility. Using the QIAgility software, we have optimized a protocol that works for all nanoplate types and QIAcuity applications. Here we report the performance of a front end automated QIAgility dPCR nanoplate setup procedure for use with the QIAcuity dPCR system.

The QIAcuity digital PCR system combined with the QIAcuity One-Step Viral RT-PCR Kit enables precise detection and quantitation of vector-borne viruses in mosquitoes. The results presented in this comparison study showed that digital PCR is a powerful tool for absolute quantitation of low abundant targets and is a more reliable detection method than qPCR. Multiplexing allows detection and quantitation of multiple targets in a single reaction more efficiently by increasing sample throughput at a reduced cost per target.

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.

Q-Solution is an innovative and versatile PCR additive that works in part by lowering the melting temperature of DNA. Adjusting template melting properties can be useful when interrogating DNA with high-GC content or with complex secondary structures, such as adeno-associated virus (AAV) genomes. Q-Solution has additional properties that can be used to mitigate the carryover of various PCR inhibitors. This application note will highlight a few examples of how the Q-Solution Kit can be used in QIAcuity workflows.

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.

Here we compared the performance of qPCR and the nanoplate dPCR techniques. The digital PCR method on the QIAcuity significantly improved precision when measuring copy number states and sensitivity of mutation detection through absolute quantification and reduced standard error. This is advantageous in various applications, including copy number variation analysis, small fold-change and rare mutation detection.

Here we demonstrate how to optimize your assays on a microfluidic nanoplate-based digital PCR system, the QIAcuity, and provide recommendations for a seamless transfer. Moreover, the QIAcuity dPCR workflow is very similar to qPCR.

A versatile workflow for the detection of low-abundance microbes

The QIAcuity Software Suite enables the user to set up plates, analyze results, and monitor the status of runs in real time. For this configuration, the QIAcuity instrument needs to be connected to a network through Ethernet. Alternatively, a direct cable connection between the QIAcuity and the notebook where the QIAcuity Software Suite is running needs to be established. When connected to a network, up to 10 users may access the QIAcuity Software Suite via a browser installed on the client PC (Windows or Mac).

The following browsers are supported in the QIAcuity Software Suite:

-Mozilla Firefox (version 64.0.2 or higher)
-Microsoft Edge (version 44.17763.1.0 or higher)
-Google Chrome (version 71.0.3578.98 or higher)

The new QIAcuity Software Suite 1.2 offers a functionality that enables users of the QIAcuity Software 1.1.3 to upgrade to the new version while keeping the library of previously stored plate runs.

Note: If you have exported plates from QIAcuity Software Suite 1.1.3 that you would like to import and use in QIAcuity Software Suite 1.2, you will need to import the plates before upgrading from version 1.1.3 to version 1.2. You may then export the plates again. Future software version starting from QIAcuity Software Suite 2.0 will facilitate import of plates from previous QIAcuity Software Suite versions.

The new improvements are as follows:

-Support for the Nanoplate 8.5k 24-well
-Hyperwell functionality to combine several wells to one combined well for analysis
-Automated plate archiving functionality
-Functionality to show the number of single/double positives in 2D scatterplots
-VPF (Volume Precision Factor) to further improve concentration calculation (see related resources)
-Additional improvements for stabilization and troubleshooting

Version 2.2

The new Version 2.2 of the QIAcuity software (QIAcuity Software Suite v 2.2 and QIAcuity CSW v 2.2.) offers improvements for users working under GMP by adding a user ID validation during the report signing and the addition of timezone offset stamp for audit trail entries and for result report data. Furthermore, the addition of a standard deviation and coefficient of variance calculation in percentage of mean concentration calculation for replicates where implemented. In addition, the instrument camera stability was improved and an internal validation method was implemented.

Detailed information about the QIAcuity Control Software version 2.2 is available in the Release Note, which can also be downloaded under section “Software Release Notes”.

Note: The latest CSW version 2.2 is only compatible with the Software Suite version 2.2. If only one software component is updated, no connection between the Software Suite and the CSW can be established.

Important: Please follow the instructions provided in the QIAcuity User Manual for software version 2.2 and in the Release Note.

It is strongly recommended to update the QIAcuity Software Suite first before proceeding with the QIAcuity Control Software.

Note: After clicking reboot during CSW upgrade or change of Suite connection, login screen may appear for short period. Please ignore it and wait for the QIAcuity instrument to shut down and restart itself.

FAQ

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.

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.

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 ID - 9205

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.
