Targeted DNA tests
Your target species, a custom DNA test.
European mink, Atlantic bluefin tuna, sharks, loggerhead turtle: LDgenX holds primers and probes for 22 species and designs assays for new targets. Digital PCR (dPCR) detects and quantifies the DNA of the species you are looking for in water, soil or sediment.
Your scientific need
One question, one species.
A protected species to confirm, an invasive species to detect early, a pathogen to monitor? When the question is about one species, a targeted test answers it more directly than a survey.

The approaches to bring in
Detect, quantify, monitor.
The choice of methods is guided by the scientific objective and the context of your project.
Detect a species
Find out whether the DNA of one species is present in a water, soil or sediment sample.
Quantify its DNA
Estimate the amount of target DNA, as a number of copies, to compare samples or sites.
Rare or invasive species
Look for a protected, threatened or invasive species when the question is about one target.
Pathogens
Monitor a pathogen by dPCR, for instance in aquaculture.

Our target species
Mammals
European mink
Mustela lutreolaPrimers and probes held in-house
LDgenX holds primers and probes for this species. Tell us about your project so we can define a suitable approach together.
Sample matrices, conditions of use and assay performance are evaluated for each project.
Discuss this targetThe steps of developing an assay
Specify the species, the question asked and the related species not to be confused with it, from the available reference sequences.
dPCR estimates a quantity of target DNA, as a number of copies; it does not directly count the individuals present.
Is your species not on the list?
Tell us about the species, your question and your samples: we will look with you at developing a suitable assay.

Shared scoping. A tailored proposal.
Each test is defined with you: the species, the related species it must not confuse, the matrices and the sampling plan. Assay performance is evaluated for each project.
To prepare the first conversation
- Your objective and the decision it should inform

- The samples or data already available
- Your schedule and field constraints
What we define together
- The scope of the service
- The sampling strategy and the analyses
- How results are reported
- The schedule and the quote
