Biocept - Blood Collection Tube (BCT) for cfDNA and CTCs - Brochure

As healthy and diseased tissue interact with the bloodstream, they release both cellular and genetic material into the circulation. These materials are referred to as “cell-free” DNA (cfDNA), and circulating tumor cells (CTCs). Conventional blood collection tubes contain only anti-coagulants, designed to prevent blood clotting. Over time, and without stabilization, nucleated blood cells lyse and release their genetic components into the blood. As a result, levels of cfDNA increase, which can prevent the detection and quantification of abnormal genetic material (i.e., circulating tumor DNA).
