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.
