Converting SNPs to CAPS and dCAPS Marker Using dCAPS Finder


Sungwoo Lee, The Ohio State University

This tutorial provides an overview of CAPS and dCAPS markers as well as the steps required to design CAPS and dCAPS markers from previously identified SNPs using dCAPS finder software.


Single Nucleotide Polymorphism (SNP) markers can be converted to Cleaved/Cut Amplified Polymorphic Sequence (CAPS) markers if the polymorphism alters a restriction enzyme cutting site. If a polymorphic restriction enzyme cutting site is inserted, the markers are referred to as derived CAPS (dCAPS). This tutorial introduces users to dCAPS finder software, which can be used to design CAPS and dCAPS markers. In the event that the slideshare tutorial does not work, the tutorial is also attached as a pdf at the bottom of the page.
