The Natrix natrix detection kit comes with then new eDNA qPCR hot start mix. This qPCR hot start mix provides excellent performance for sensitive, robust and accurate qPCR detection assay.  The eDNA qPCR hot start mix is ​​highly resistant to inhibitory factors, such as humic acids present in environmental samples. This kit contains primers and a probe to detect a highly specific region on the mitochondrial DNA of the species Natrix natrix.

Detection as a service:

We offer the detection of Natrix natrix also as a service. See our eDNA service website (in English or in Dutch) or contact us for more information about sampling, sending and pricing.

Common species names:

  • English: Grass snake
  • German: Ringelnatter
  • French: Couleuvre à collier
  • Dutch: Oostelijke ringslang

Kit properties:

The Natrix natrix detection kit has:

  • High resistance to inhibiting factors. Environmental DNA (eDNA) extracts contain often multiple qPCR inhibiting factors. Normal qPCR master mixes are sensitive to these substances.
  • Strong fluorescence signal with low background noise. Isolated environmental samples contain residues of naturally occurring auto fluoresce substances that will interfere with the measurements. Environmental samples needs a strong fluorescence signal from the assay in order not to experience background interference.
  • Highest possible sensitivity (1 DNA copy per reaction). Environmental water samples may contain very low amounts of target DNA.
  • 100% specificity. Isolated DNA from environmental samples contains billions of DNA fragments from bacteria, protozoa, plants, animals, etc. Not only animals from the same order (fish, amphibians, reptiles, mammals, etc.) must be taken in account during primer/probe design, but all known DNA sequences must be checked for nonspecific binding of the primers and probe.
