Genomic DNA handling and the Agilent Femto Pulse system

5 Jun 2023

In this application note, Agilent Technologies discusses the significance of genomic DNA (gDNA) integrity in molecular biology labs. Maintaining high-quality samples is crucial to generating reliable results and saving time and resources. Various factors such as extraction techniques, storage conditions, and mixing can affect gDNA sample integrity. Pulsed field gel electrophoresis (PFGE) is commonly used for quality assessment but requires significant sample quantities and overnight runs. Agilent Femto Pulse system with Genomic DNA 165 kb kit is a faster and cost-effective alternative that offers high sensitivity and resolution. This note examines the impact of different handling protocols on gDNA sample integrity and provides recommendations for best practices when using the Femto Pulse.

DNA / RNA Extraction and PurificationPurified DNA and RNA are required for numerous downstream molecular biology applications. Consequently, the importance of high-quality DNA/RNA extraction and purification equipment cannot be underestimated. Many purification kits are available and are typically optimized for nucleic acid type and source, including plasmid DNA, genomic DNA, mRNA, RNA and viral nucleic acid purification kits. Automated extraction and purification of nucleic acids can be implemented with magnetic bead separator instruments or high-throughput purification workstations.

Nucleic acids can be detected by labeling with colorimetric, fluorescent or radio labels and using in situ hybridization kits to identify specific sequences. Multiple nucleic acids can be detected and quantified at once using RNA / DNA detection beads or RNA / DNA microarrays.

Electrophoresis equipment includes horizontal and vertical gel electrophoresis chambers, isoelectric focusing systems, 2D electrophoresis and capillary electrophoresis instruments. Precast gels with a gradient can be used or gels can be hand cast. Samples are run alongside ladders or markers to identify the approximate size of a molecule. Separated proteins and nucleic acids in the gel can be stained or probed with fluorescent markers and then imaged and detected using gel documentation instruments, transilluminators, densitometers and scanners.
