The QIAcuity dPCR System, complemented by the QIAcuity Software Suite version 2.5 and higher, offers a powerful solution for determining DNA integrity and stability. Analyzing up to 5 targets simultaneously enables accurate and precise integrity assessment. The importance of determining genome integrity becomes particularly evident in analyzing viral vectors such as AAVs, which are known for their susceptibility to packaging errors. Moreover, dPCR is a valuable tool for assessing DNA stability, providing valuable insights into storage and processing impacts.

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.

Digital PCR (dPCR) is a powerful technique that detects and quantifies ultra-rare mutations in a high background of wild-type cfDNA down to 0.1% variant allele frequency. Here, we describe end-to-end manual and automated workflows that enable accurate detection and absolute quantification of ultra-rare PIK3CA variants in cfDNA using the QIAcuity Digital PCR System.

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.

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.

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.

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

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.

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.

FAQ ID - 9198

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

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).

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.
