Simple DNA Extraction

The easiest DNA extraction procedures are based on a chelating resin and do not necessitate multiple tube transfers for most types of samples. They provide a very rapid and cheap way to isolate DNA from degradative enzymes and from some of the potential contaminants that might inhibit experiments, leaving DNA in solution. Although this type of extraction is not appropriate for complex samples (e.g. faeces, eDNA) or in situations where long-time storage is required, it is ideally suited for soft bodied tiny animals (e.g. aphids, fruit flies, tissue samples ect.) which are processed immediately.

 

Automated DNA Extraction

For this type of extraction DNA is reversibly bound on paramagnetic beads and therefore separated from other cell components and finally released into PCR plates. This procedure is semi-automated, leading to a low risk of cross-contamination between different samples. Because of automation the method is ideally suited for high-throughput and therefore goes along with sample processing at high speed. The automated DNA extraction provides high quality DNA even from complex samples. DNA extracts can also be stored for long periods, thus providing the possibility for additional analyses at a later date.
