8 facts most people don’t know about DNA from saliva

Posted by Scott Rabuka on Fri, Feb 01, 2019 @ 10:02 AM

Since the launch of this blog, The Genetic Link, in 2009, we have published numerous articles, interviews, technical information and infographics to share what we know about DNA from saliva. Saliva is the human body’s most accessible bio-fluid but, after 7 years, we continue to be surprised at how often we hear wrong perceptions about this robust and easy to access sample type.  It’s time to set the record straight on DNA from saliva once and for all. Are you ready? Here are 8 facts about DNA from saliva that most people don’t know.

The key to eliminating bias in genetic studies could be in our spit: expert panel discusson

Posted by Erin Carpenter on Wed, May 16, 2018 @ 14:05 PM

Are you questioning what sample-type to collect for your genetic research project? Are you considering saliva for DNA, RNA, or epigenetic analysis? What should you consider when making this selection and what challenges might you face?

More DNA samples in less time for BRCA 1 and BRCA 2 research project

Posted by Shauna White on Thu, Jul 31, 2014 @ 13:07 PM

Obtaining DNA samples in sufficient numbers and in a timely manner can be a barrier to achieving statistical relevance for research studies. Maximizing recruitment means making sample collection easy and convenient for donors. Recently the Basser Research Center for BRCA at the University of Pennsylvania successfully used event-based collection to rapidly grow the number of participants in their research project.

Oragene as a solution for international DNA sample collection

Posted by Nicholas Ramdass on Tue, Oct 22, 2013 @ 09:10 AM

The author of this article, Nicholas Ramdass, is a Sales Manager at DNA Genotek Inc.

Oragene is truly a DNA collection device that has a global impact. Currently, Oragene is used for the non-invasive self-collection of DNA from saliva in more than one hundred countries and on six continents. As a salesperson at DNA Genotek, I have the privilege of working with some of the world’s leading researchers who are studying every aspect of genetics from mental illness to cancer, and from chronic health issues to the very rarest of diseases. My favorite part of my job has always been helping researchers find solutions for projects with complex collection logistics, especially those that transcend international boundaries.

Sneak preview of DNA Genotek at ASHG 2012

Posted by Debra Ereaut on Fri, Nov 02, 2012 @ 11:11 AM

Once again, we are all very excited to attend the American Society for Human Genetics (ASHG) annual meeting in San Francisco from November 6th through to the 10th. We always look forward to this conference which brings together over 5,000 delegates from all areas of genetic research. We are pleased to be one of the 200 exhibiting companies and as such, we have planned a few special events. So, if you are looking to organize your agenda for this years’ ASHG meeting, check these details out.

Saliva samples as a source of DNA for high throughput genotyping

Posted by Shauna White on Tue, Jul 03, 2012 @ 10:07 AM

The BMC Medical Genomics Journal recently published the results of a study titled “Saliva samples are a viable alternative to blood samples as a source of DNA for high throughput genotyping”. The study examined the feasibility of collecting DNA from saliva as a non-invasive, economical substitute to DNA from blood samples for use on genome-wide arrays. The two arrays used for the study were the Applied Biosystems Taqman™ and Illumina BeadChip arrays.

Solving genetic mysteries with DNA from saliva

Posted by Shauna White on Thu, May 31, 2012 @ 10:05 AM

Dr. Hugh Rienhoff is well known as a technology visionary, entrepreneur, and venture investor in life sciences. In addition to his current role as CEO of FerroKin BioSciences, and his appointment as a Visiting Scientist at the Children’s Hospital Oakland Research Institute, he has also founded the nonprofit organization MyDaughtersDNA.org, a community focused on aiding those with diagnostically challenging genetic conditions. It was not simply that he was a trained clinical geneticist and had the background and resources to spur this effort. The motivation was simple: Dr. Rienhoff ‘s daughter was born with an unknown genetic disorder. She exhibited a puzzling array of symptoms including small muscles -- no one is sure what might lie in her future because no one is sure what is wrong with her.

Supercentenarians’ DNA keeps the grim reaper at bay

Posted by Shauna White on Wed, May 02, 2012 @ 10:05 AM

The remarkable growth in the number of centenarians (people aged ≥ 100) has garnered significant attention over the past 20 or so years. Centenarians have been found to exhibit marked delays in functional decline and age-related lethal diseases such as heart disease, cancer, and stroke. Recently, an even more extreme group, supercentenarians, or people aged 110 and older, has begun to yield sufficient numbers to warrant study. Supercentenarians are living proof that reaching a ripe old age doesn't necessarily mean that you can no longer take care of yourself. Consequently, the interest in genetic studies of these super centenarians is growing.

It’s Movember at DNA Genotek

Posted by Shauna White on Tue, Nov 01, 2011 @ 16:11 PM

“Movember” (the month formerly known as November) is a moustache growing charity event held throughout November each year that raises funds and awareness for men's health. Movember is responsible for the sprouting of moustaches on thousands of men’s faces around the world. Since its humble beginnings in Melbourne Australia, Movember has grown to become a truly global movement inspiring more than 1.1 Million Mo Bros and Mo Sistas to participate, with formal campaigns in Australia, New Zealand, the US, Canada, the UK, Finland, the Netherlands, Spain, South Africa and Ireland. In addition Mo Bros and Mo Sistas support the campaign and men’s health cause across the globe, from Russia to Dubai, Hong Kong to Antarctica, Rio de Janeiro to Mumbai, and everywhere in between.

Nature versus nurture: What's your opinion?

Posted by Erin Carpenter on Tue, Oct 25, 2011 @ 10:10 AM

We are all familiar with the role genetics play in shaping our physical appearance. You might have inherited your mother’s green eyes or your father’s broad shoulders. We too understand how genes influence our risk or resilience to developing various conditions. In previous The Genetic Link blog features we’ve linked genes with substance abuse, cancer, epilepsy and tropical diseases. But what I’ve been pondering lately is how and to what extent our unique genetic code is involved in making us who we are by shaping our personality, behavior, social interactions and thought processes. Perhaps you’re familiar with the idea of nature versus nurture, or gene versus environment studies. What I want to know is how much of who I am is due to my genetic make-up versus  how much is a result of that complicated mix of my early experiences, social and cultural influences, family interactions, education…in other words, my environment? These almost philosophical questions are tackled on a daily basis by psychologists, psychiatrists and neurologists; and I am absolutely riveted by this research.
