Designing KASP (Kompetitive Allele-Specific PCR) markers for genotyping involves several key steps. First, identify the target SNP (Single Nucleotide Polymorphism) for genotyping. Then, design allele-specific primers that specifically amplify each allele.

These primers should have a competitive element, typically a tail or a universal tag, to allow discrimination between alleles during the competitive PCR step. Validate primer specificity and efficiency using appropriate controls. Finally, optimize PCR conditions for genotyping accuracy and reproducibility.

For designing PCR primers compatible with KASP technology, several software tools are available. KASP Designer by LGC Biosearch is a widely used and reliable tool for designing KASP assays.

It helps design allele-specific primers and provides information on potential amplicon size and SNP position. Another option is Primer3, a versatile primer design tool that can be configured for KASP primer design by specifying parameters such as allele specificity and competitive tails. Both tools are accessible online and can assist in the efficient design of KASP markers for genotyping purposes.
