The future belongs to those who believe in the beauty of their dreams, said Eleanor Roosevelt, First Lady of the United States, 1932-1944. The science of the molecular biology of the gene is now more than 60 years old and in fact, the new goals and new dreams are just beginning.

Recent Publications That Utilize Cell-Free DNA

Posted by Luke Doiron on Sep 20, 2016 2:00:00 PM


When cells die, they leave behind tiny amounts of highly fragmented DNA that circulate in plasma. This cell-free DNA (cfDNA) contains the evidence about disease processes and physiological conditions affecting tissues throughout the body. Consequently, cfDNA provides a non-invasive “liquid biopsy” and a promising biomarker for cancer and other diseases.

“One for all and all for one; that is our device,” wrote Alexandre Dumas over a hundred years ago in the famous novel, The Three Musketeers. The devotion to working together and teamwork is equally as critical in the present and bright future of new genomics technologies such as tissue microarray (TMA) devices.

Creating Targeted Next-Gen Sequencing Panels from FFPE Samples

Posted by Luke Doiron on Aug 30, 2016 8:00:00 AM


Next Generation Sequencing (NGS) technologies yield a fast-forward from the completion of the Human Genome Project (1990-2003) with the laborious, slow Sanger methods described in the late 1970s to the precision medicine trending now. NGS users, like the fictional characters in Star Trek: The Next Generation, can “boldly go where no one has gone before.” In the same way, people who use NGS methods currently can sequence one person’s genome in its entirety in just one day.

Changes in Peripheral Blood Over a Person's Lifetime

Posted by Luke Doiron on Aug 25, 2016 8:00:00 AM



Investigating the composition of peripheral blood of an individual can provide a window for both innate and outside experiences. While genetics will certainly influence composition, experiences like stress, disease, smoking and infection will also have an impact. Researchers studying cells isolated from peripheral blood donors need to be aware of the diverse influences that can affect their baseline. Some examples of these are outlined below.
