EFFICIENT gDNA EXTRACTION WITH THE PROMEGA RELIAPREP™ LARGE VOLUME HT gDNA ISOLATION SYSTEM

Efficient gDNA extraction with the Promega ReliaPrep™ Large Volume HT gDNA Isolation System – tailored to your DNA biobanking needs Tecan and Promega are partnering to provide a uniquely efficient and reliable system for isolating genomic DNA from large volumes (1-10 ml) of blood, typically drawn into a standard 10 ml Vacutainer tube. The combination of the Freedom EVO, the ReliaPrep™ HSM and the ReliaPrep™ Large Volume HT gDNA Kit allows automated recovery of pure gDNA from up to 32 blood samples (each up to 10ml) in four hours.

Programming and running a Nucleic Acid Purification workflow can be done with greater speed, simplicity and process security using the intuitive TouchTools touchscreen interface from Tecan and the customizable TouchTools NAP wizard for magnetic bead or vacuum-based nucleic acid purification protocols.

The DreamPrep NAP workstation featuring Zymo Research solution is based on the Fluent® 480 Automation Workstation in combination with Fluent Gx Assurance Software. The system is configured for nucleic acid extraction workflows using magnetic bead-based procedures.

Nucleic acid purification workflows have been developed and tested in collaboration with Zymo Research to deliver preprogrammed nucleic acid extraction workflows using Quick-DNA MagBead Plus Kit, ZymoBIOMICS 96 MagBead DNA Kit and Quick-DNA/RNA Viral MagBead Kit. This set-up allows processing of 1 to 96 samples at a time, with optional barcode scanning for samples and reagents.

Optional quantification and normalization of nucleic acid content is easily achieved with integrated reader options.

Nucleic acid quantification and normalization is required in most genomics workflows, most commonly after the initial nucleic acid purification step, but consumes precious sample and can be tedious when performed manually. The versatility of the classical UV absorbance-based technique still makes it the ‘go to’ method for many applications, as it allows the concentration of all DNA and RNA types to be measured (based on the specific empirical extinction coefficient for each nucleic acid type) and provides simultaneous assessment of samples for impurities that could impair downstream applications.

The Frida Reader is an add-on module for the Fluent Automation Workstation that revolutionizes the way quantification and normalization are performed. It allows samples to be measured in a hanging drop at the end of a disposable pipette tip, completely eliminating sample loss for nucleic acid quantification.

The automated workflow for the Quick-DNA MagBead Plus Kit on the DreamPrep NAP workstation featuring Zymo Research provides a complete, walkaway DNA extraction solution from a variety of sample types, such as blood, saliva, tissue and cultured cells. It offers consistent and reproducible DNA recovery, with purities comparable to manual extraction. The results presented in this application note demonstrate that the workflow eliminates cross-contamination, generating ultra-pure DNA that can be used for any downstream application, including qPCR and NGS sequencing.

The DreamPrep NAP workstation featuring Zymo Research offers complete walkaway extraction of high quality, sequencing-grade DNA from a wide variety of microbiome sample types, providing an effective solution for reliable, high throughput and hands-free DNA purification. This plug-and-play solution delivers unbiased, consistent and reproducible DNA yields and purities, with no cross-contamination observed. The data presented in this application note demonstrates the successful recovery, excellent reproducibility and consistency between sample preparations when evaluating the yield, concentration, and purity of the extracted DNA.

The DreamPrep NAP workstation featuring Zymo Research offers complete walkaway extraction of viral DNA and RNA from plasma or serum samples. The results presented in this application note demonstrate efficient recovery of viral DNA and RNA in a consistent and reproducible manner. The automated extraction workflow is equivalent to manual extraction in terms of total nucleic acid recovery, successfully extracting viral RNA from samples containing as little as 60 viral copies, with lower CT values. This workflow shows no cross-contamination and can achieve high quality viral DNA from a variety of samples (eg. plasma and serum). The resulting viral RNA can be used for sensitive downstream applications, such as RT/qPCR and next generation sequencing.

Extraction of genomic DNA from the whole blood is a common first step for a variety of downstream applications such as PCR or next generation sequencing protocols. The Maxwell HT 96 gDNA Blood Isolation System (Promega) offers rapid isolation of genomic DNA from whole blood based on magnetic beads technology. The protocol is fully automated on a Fluent Automation Workstation with FluentControl™ software which together with TouchTools™ user interface (UI) and Smart Commands ensure reduced complexity and flexibility of the workflow set up. As a result, the automated run delivers consistently high and uniform DNA yields in a reliable and reproducible manner, with minimal hands-on time.

Extraction of plasmid DNA is a standard procedure in molecular biology laboratories around the world, and plasmids are still a go-to resource for cloning and modifying genes of interest. For protein production applications, large volume bacterial cultures are often required, creating a need for efficient purification techniques capable of generating large quantities of the plasmid of interest. Promega’s Wizard MagneSil Tfx System automated on the Freedom EVO workstation offers a rapid and simple method for isolating transfection-quality plasmid DNA in a high throughput format to establish a flexible, fully automated solution for the purification of plasmid DNA, streamlining laboratory workflows and providing fast and reliable extraction of high purity DNA.

There is increasing demand to purify genomic DNA (gDNA) from human blood and saliva at small scale and high throughput using liquid handling platforms. Promega’s ReliaPrep 96 gDNA Miniprep HT System is designed for automated recovery of gDNA from 100-350 μl of human whole blood or 350-700 μl of human saliva, for research use only, not for use in clinical diagnostics. Full automation of the gDNA purification process on a Freedom EVO® workstation streamlines laboratory workflows and provides reliable, rapid extraction of highly pure gDNA.

Extraction of plasmid DNA using the QIAprep 96 Turbo and QIAprep 96 Plus protocols on the Resolvex A200 positive pressure workstation results in high purities and comparable yields to the reference methods demonstrating the suitability of this system for routine use in high-throughput labs. The faster QIAprep 96 Turbo protocol reduces sample transfer steps and hand-on time but results in lower yields compared to the QIAprep 96 Plus protocol. The QIAprep 96 Plus protocol delivers higher plasmid DNA yields with lower variation, but it requires additional sample handling steps. The Resolvex A200 workflow reduces handling times and errors compared to the reference method by providing direct dispensing of all buffers and consistent pressure gradients.

AGRANIS is a service laboratory in Laval, France, that specializes in milk sample analysis using an innovative automated technique for determining the somatic cell count (SCC) of each cow in a herd from a bulk tank milk sample called GénoCellules®. The SCC is quantified as the number of cells/ml of milk, and is used as an indicator of quality. Generally, the SCC is determined by flow cytometry, requiring analysis of individual milk samples from each cow in a herd, which involves a large number of samples. However, prior genotyping of cartilage samples from each cow in a herd makes it possible to subsequently determine the SCC of each cow in a single bulk tank milk sample.

As part of this process AGRANIS uses Nucleospin Tissue 96 kits (Macherey-Nagel) for DNA extraction of both cartilage and bulk milk samples on a Fluent® Automation Workstation equipped with an eight-channel Air FCA™, a Robotic Gripper Arm™, a BioShake® 3000-T elm (Quantifoil Instruments) for heating, shaking and homogenization of samples, and a Te-VacS™ module with a customer-specific suction force profile to optimize the process. The automated protocol has enabled AGRANIS to carry out twice as many analyses in the same time as with their previous approach. The enhanced speed enables reliable batch processing of 96 samples in just two hours, and several plates per day.
