eDNA analysis (Environmental DNA)
Environmental DNA (eDNA) analysis is a technique that makes it possible to study the prevalence of different microbe, fungi, and animal species in the environment through the DNA they shed in it.
DNA residues can be extracted from environmental samples including water, sediment, or soil. The samples are collected into the filters according to the separately agreed sampling plan. After extraction, polymerase chain reaction (PCR) is used to increase the abundance of DNA in the sample. The DNA is then sequenced using automatic sequencer instruments and compared to a database of known DNA sequences to identify the species it originated from.
Examples of eDNA testing applications include:
Monitoring the presence of endangered or invasive species within a habitat.
Evaluating soil quality by studying the prevalence of indicator species, such as microbes and fungi.
Gathering data for an environmental impact assessment before a large-scale infrastructure project to minimize harm to vulnerable species.
The price of the analysis depends on the target species and the extensiveness of the project. Please describe these in detail when requesting an offer.
