KASP genotyping reagents

Make data-informed breeding decisions faster with our proprietary KASP PCR-based genotyping assay.


Kompetitive Allele Specific PCR (KASP™) assays enable accurate, bi-allelic discrimination of SNPs and indels. Unmatched quality, reliability and credibility have established KASP as a foundational SNP genotyping chemistry for agrigenomics.

  • Accurate: KASP has been independently verified to achieve a 99.8% call rate across many DNA extraction techniques, GC/AT-rich templates and plant species.
  • Cost effective: KASP does not require expensive labelled assay-specific primers or probes, is compatible with crude DNA extraction methods and uses low reaction volumes.
  • Flexible assay design: Our experts will identify the best mix of three non-labelled primers for your SNP, indel or mega indel.
  • Open plate reading format: The signal can be read on most FRET-capable plate readers and qPCR instruments. We have downloadable step-by-step protocols for running KASP assays on a wide range of commonly used qPCR instruments.

Pre-designed KASP assay panels

In collaboration with scientific partners across the globe, we have developed a number of KASP™ genotyping panels for various species. These pre-designed libraries are cost effective and easy to run with no minimum order quantity.


Unlike chip-based systems with fixed marker sets, our KASP genotyping panels allow you the flexibility to select markers in response to the dynamic nature of marker-assisted breeding projects.
