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.

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.

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.

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 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.

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.

Fast. Scalable. Reliable.

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.

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).

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.
