Designing a CAP Marker From a SNP Using the SGN CAPS Designer

Authors:

Matthew Robbins, The Ohio State University; Heather L. Merk, The Ohio State University

This tutorial provides a general explanation of a CAP marker and demonstrates how to design a CAP marker from a previously identified SNP using the Sol Genomics Network (SGN) CAPS designer tool.

One method for SNP detection is to create a cleaved amplified polymorphic (CAP) marker. A CAP marker is a simple PCR-based molecular marker assay visualized by agarose gel electrophoresis.

This tutorial provides a general explanation of a CAP marker and demonstrates how to design a CAP marker from a previously identified SNP using the Sol Genomics Network CAPS designer tool. In the event that the slideshare tutorial does not work, the tutorial is also attached as a pdf at the bottom of the page.
