We offer variety identification (variety fingerprinting) services for several crops. Our lab can create a reference genetic fingerprint of your material (seed or plant), store it in our database, and compare it to that reference as you submit subsequent samples for analysis. We have high-throughput equipment, including automated liquid handlers for DNA extraction, Hydrocyclers for PCR, and 96-Well Capillary electrophoresis for fragment analysis.
Variety Identification (Fingerprinting) by SNP or SSR Markers
Hybrid Purity by Markers
We use PCR technology to test the purity of your hybrids by identifying a set of typically 12 SNP (single nucleotide polymorphism) markers that work with your material. We can then run the analysis for 46 or more seeds per sample, based on your requirements.
DNA Markers
Our lab uses SSR (simple sequence repeat) and SNP (single nucleotide polymorphism) DNA markers. Depending on the type of material (i.e. which crop, whether it’s seed or plant tissue, etc.), we select the appropriate technology to perform analysis. Our lab is equipped to perform either capillary electrophoresis (CE), Taqman genotyping, or Kompetitive Allele Specific PCR (KASP) techniques. We are able to adapt to customer requirements if one technology is preferred over another.
