3 reasons DNA from saliva is ideal for GWAS

Posted by Shauna White on Tue, Apr 05, 2011 @ 13:04 PM

With the growth of genome wide association studies (GWAS) and their need for DNA from many thousands of people, the time seemed right for us to highlight how DNA from saliva enables GWAS. DNA from saliva is allowing more researchers to achieve their recruitment numbers for GWAS studies while providing results that are equivalent to blood on downstream assays. Saliva is a highly accessible body fluid that is easy to collect when collected with Oragene. Since the launch of the Oragene product in 2004, there have been many published research studies that have shown this to be true. Recently, Bahlo et al of the Australian and New Zealand Multiple Sclerosis Genetics Consortium (ANZgene) published a paper that showcased how DNA from saliva performed on the Illumina Infinium Hap370CNV DUO microarray[1] and highlighted why it is ideal for GWAS.

Research Study Validates Oragene•ANIMAL for Canine GWAS Studies

This month, PLoS ONE published a new research study that I think will interest readers of The Genetic Link. The study, titled "Array-Based Whole-Genome Survey of Dog Saliva DNA Yields High Quality SNP Data", was written by Jennifer S. Yokoyama, Carolyn A. Erdman and Steven P. Hamilton of the Department of Psychiatry and Institute for Human Genetics, at the University of California, San Francisco. The study is interesting for several reasons.

DNA Genotek's Top 10 List for 2009

Posted by Ian Curry on Mon, Jan 04, 2010 @ 14:01 PM

I have to admit, coming up with DNA Genotek's "Top 10 list for 2009" was more difficult than I imagined it would be. There are so many great things that happened in the past year - in our company, with our customers, and in the field of genetics - but I think I've narrowed it down to those that are most significant.
