The infection of human immunology viruses (HIV) occurs by integrating its genome into infected cells to enter an inactive state of reversible latency that evades anti-retroviral therapy. The capacity to sequence such a provirus ...
Using a routine blood sample, investigators have developed an extremely sensitive assay to detect and quantify DNA fragments containing rare genetic mutations in a patient's cancer cells. This assay uses "SuperSelective" ...
