Nucleic Acid Purification

The purification of cell-free DNA (cfDNA) is challenging because of the low concentrations, its instability and the small fragment sizes. Nevertheless the information it delivers is highly valuable for cancer studies and research of prenatal testing using technologies as NGS and ddPCR. The chemagic™ cfDNA kits enable the automated and efficient extraction of cfDNA from 0.5 - 5 ml plasma in 24-well or 96-well format in maximal 2 hours with minimal hands-on time. The chemagic cfDNA kits show equivalent yields as well as purities compared to the manual silica based gold standard kit. Features of the chemagic cfDNA Purification Workflows chemagen developed the chemagic cfDNA kits to isolate cfDNA from 0.2 - 18 ml fresh and frozen plasma derived from EDTA, citrate or other blood collection tubes within 90 - 120 minutes with the chemagic 360 instrument . The chemagic cfDNA kits are based on chemagen technology using M-PVA Magnetic Beads for the isolation of cfDNA. The cfDNA binds to paramagnetic beads, which are magnetically separated from the sample material. During subsequent steps, contaminants are removed and the purified cfDNA is transferred into an elution medium. The automated sample processing by the chemagic 360 instrument excludes cross-contamination and ensures safe handling of infectious sample material.

The success of sensitive downstream genomic applications such as qPCR depend on robust and reliable upstream sample preparation, which often includes proper sample/tissue homogenization and nucleic acid extraction. As the lab scales their sample throughput and their need for consistency in complex workflows, many have integrated automation-enabled protocols into their workflows. In this application note, a semi-automated workflow for nucleic acid extraction from liver tissue is presented, which leverages the Omni Bead Ruptor Elite bead mill homogenizer with the chemagic 360 nucleic acid extractor, with optional use of a JANUS automated liquid handling workstation.

Next-generation sequencing (NGS) has revolutionized the field of genomic research. The dropping costs and technology improvements have made feasible the application of NGS to high-throughput studies, providing a new and powerful tool to scientists working in fields as diverse as plant biology and human genetics. A crucial step in the NGS workflow is the preparation of the library for sequencing. A poor-quality library can lead to profound technical artifacts that might influence the results and, ultimately, data interpretation. The isolation of pure high molecular weight DNA or full-length RNA and a consistent and robust fragmentation protocol are the foundations to successful library preparation. To ensure that both conditions are met, chemagen has integrated the Covaris® Focused-ultrasonicator to its nucleic acid purification workflow. By exploiting the chemagic™ technology, ensures optimal extraction of DNA and RNA from a wide range of sample types. The purified nucleic acid is then fragmented using the Covaris® Focused-ultrasonicator. The integration of the Covaris® system with the chemagic™ workflows ensures unparalleled high-throughput capabilities from primary sample to DNA and RNA fragments of the desired size ready for library preparation.

With automation being increasingly employed in laboratories performing nucleic acid purification, a more consistent quality of nucleic acids is generally expected. A high quality of should also be obtainable with automation to meet requirements of demanding downstream assays such as NGS, long read sequencing, and MLPA, while ensuring long-term storage stability. However, differences in mechanical processes and kit chemistries between commercial automation platforms may result in varying qualities of nucleic acid which can impact downstream results. Here, we evaluated two systems of magnetic bead-based automated nucleic acid purification using blood samples. High molecular weight DNA acid quality was assessed in terms of yield and purity. Integrity of DNA as seen by the extraction efficiency of HMW DNA was also assessed. Extraction performance from blood based on DNA yield, purity, and integrity (DNA length) was compared between two automated nucleic acid extraction systems. The chemagic™ 360 instrument extracted pure DNA at higher yields and integrity with chemagic™ DNA Blood 400 Kit H96 (CMG-1091) or chemagic DNA Blood 4k Kit H24 (CMG-1074). A greater HMW DNA extraction efficiency was obtained with the chemagic 360 instrument that can improve performance in long-read sequencing as well as long-term storage stability.

For many years it was thought that there were just three types of RNA: mRNA, transfer RNA (tRNA), and ribosomal RNA (rRNA). However, in recent years, researchers have begun to realize that there are many other types which play key roles in cellular processes. Interestingly, deficiencies in mRNA or ncRNA have been linked to certain neurodegenerative and neurodevelopmental disorders. Dr. Jeffrey Kieft, from the University of Colorado School of Medicine, is developing a way to engineer viral RNA and subsequently reduce the rate at which mRNA is destroyed by enzymes in cells. He sees this application as a potentially powerful research tool for neuroscientists, and perhaps even the foundation for therapies of the future.

Plants are essential to our diet and ecosystem; researchers are constantly working to better understand their genetic makeup and diversity. Traditional enzymatic lysis methods to extract plant DNA are time-consuming and can be inconsistent due to the toughness of their cell walls. Physical disruption via bead mill homogenization can be an efficient alternative to both rudimentary enzymatic and manual methods. We review the workflow and determine yields from staple crops such as corn, rice, and wheat in this application note. Automation-enabled solutions help scale throughput while providing consistent and efficient sample preparation and nucleic acid extraction from plant material.

Corn is an important stable crop, not only as a food source for humans and livestock, but also biofuel as well other non-food products. This versability makes corn an importance resource and topic of research globally. Within agricultural science and sustainability, labs are hard at work better understanding the genetic mechanisms behind healthy growth and environmental adaptability, whether in response to factors such as climate change, availability of arable land, susceptibility to disease. With the adoption of high-throughput sequencing assessing plant transcriptomics, labs require sample prep methods that reliably allows the extraction of RNA with high integrity for downstream assays, which can be challenging due to thick polysaccharide cell walls and the layers inherent to certain sample types. Semi-automated tabletop bead mills allow for repeatability only afforded by automation-enabled techniques that feed into automated nucleic acid extractions that scales as your throughput increases.

The processing of human and animal tissue samples from experimental studies for downstream molecular analysis is a cornerstone of pre-clinical research across multiple disciplines spanning agrigenomics and disease research. Within animal anatomy, soft tissues are a vital component of not only organ-specific research, but also for providing insights into drug discovery or development work. Genomic workflows, including the critical upfront sample prep for efficient nucleic acid isolation of DNA and/or RNA is an important application area. Though there are multiple methods for tissue disaggregation and subsequent sample homogenization, bead mill homogenization is particularly effective for its ability to provide consistent and uniform homogenates via mechanical forces and cell disruption. In the same vein, the incorporation of automation into workflows reduces the risk of introducing human error and inconsistencies between samples. In this application note, an automation-enabled workflow for bead mill homogenization into an automated nucleic acid extractor is described to observe run-to-run reproducibility between the groups of samples extracted for DNA on different days using the same method.

Here Revvity and Illumina describe a streamlined, automated workflow from DNA extraction to sequence-ready libraries for metagenomic shotgun sequencing resulting in high quality data for species identification and functional profiling.
