Vargas DY, Kramer FR, Tyagi S, and Marras SAE. (2016) Multiplex real-time PCR assays that measure the abundance of extremely rare mutations associated with cancer. PLoS ONE 11, e0156546.

We describe the use of “SuperSelective” primers that enable the detection and quantitation of somatic mutations whose presence relates to cancer diagnosis, prognosis, and therapy, in real-time multiplex PCR assays that can potentially analyze rare DNA fragments present in blood samples (liquid biopsies), thereby providing information that can be used to modify therapy for individual patients, prolonging (and improving the quality of) life.
