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

Posted by Scott Rabuka on Wed, Jan 18, 2017 @ 10:01 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.

All about that base: applications of the fifth base of DNA

Posted by Lisa Gamwell on Tue, May 12, 2015 @ 13:05 PM

Methylated cytosine, also known as “the fifth base of DNA” has attracted a lot of research attention lately due to its importance in controlling gene expression. This fifth base has inspired researchers to study its impact on several diverse fields, such as oncology, neurology, psychology, forensics and even workplace health and safety. Methylated cytosine has even been used as a predictor of biological age [1].In this blog post I’d like to share a few examples of the exciting ways this “extra” base is providing new avenues for research.

Stabilize your sample: A “right from the start” Q&A

Posted by Devin Hale on Wed, Mar 11, 2015 @ 10:03 AM

In an earlier blog post we discussed the importance of reliable samples for human genomics, microbiome and infectious disease nucleic acid based applications, and how a lack of trustworthy samples can not only lead to incorrect outcomes, but also keep you from having full confidence in your results. To obtain a truly accurate outcome, a sample must be stabilized and protected from the point of collection until it is analysed downstream.

Do you know the biggest challenge in genetics?

Posted by Devin Hale on Tue, Jan 27, 2015 @ 10:01 AM

I’m sure you are familiar with the expression “Garbage in, Garbage out”. Popular in the field of computer science, it implies that incorrect or low quality input will result in correspondingly poor output. The mere existence of a result is no guarantee of its quality or accuracy, as surely as cooking with the wrong ingredients will not produce your desired dish.

Saliva DNA plays vital role in international clinical research studies run from Australia

Posted by Shauna White on Thu, Oct 03, 2013 @ 10:10 AM

Dr. Janet Coller, Lecturer at the University of Adelaide, has an established track record in Pharmacology and Pharmacogenetic medical research within the health areas of cancer, drug dependence, cardiology and solid-organ transplantation. Her research includes work to identify how genetic variability impacts the therapeutic use of tamoxifen for breast cancer, identifying important genetic variants that determine successful treatment of opioid dependence with methadone, and research in the emerging field of immunogenetics.
