Environmental DNA (eDNA) detection
If you are considering applying to the facility to support a project involving eDNA analysis we are able to advise and assist with experimental design.
Please contact Dr Deborah Dawson to discuss any application for project support at our facility.
Our equipment includes a QuantStudio 12K Flex Real-time PCR System (the all-in-one qPCR instrument). This is used for environmental DNA (eDNA) typing, such as screening water samples for the presence of a specific species, eg Great Crested Newt Triturus cristatus.
We use an Illumina MiSeq Sequencer for detecting multiple species from environmental samples, such as the detection of:
- fish species present in lakes identified from water samples
- earthworm biodiversity as a measure of soil health
- parasites or bacteria present in faecal samples, for studies of disease transmission or microbiota
- pollination - plant species represented in pollen taken from the bodies pollinator species
- prey species in faecal material (see diet analysis)
Bespoke one-to-one training and support is provided as required to design the study, complete the lab work, process the sequence data and perform the data analyses.
