Access to gene sequences may be a spit sample away

by  /  30 June 2014

DNA extracted from saliva is just as useful for sequencing genes as is DNA from blood cells, according to a report published in April in BMC Genomics. The easy and inexpensive method would be a boon for studies that need to sequence large numbers of people.
