The use of genetic marker technologies has become an integral tool for researchers working in trait development, and provides many common challenges, regardless of the species of interest. With a focus on sample preparation and genotyping technologies, the LGC workshop will provide an overview of some of the tools and systems available to overcome these challenges, and present a number of case studies demonstrating application of these tools at both the basic research level and the delivery of high volume marker validation in a parental screening population. Technologies discussed will include, high throughput DNA extraction and sample preparation, Sequence Based Genotyping (KeyGene), KASPTM based genotyping, qPCR applications and the platforms available to deliver the higher throughput required for larger scale research and production based analysis including SNPline, Nexar® and the new IntelliQube® instrument developed at Douglas scientific.
