UConn Researcher Develops Simple, Low-Cost CRISPR-based Diagnostic Test for COVID-19 |
|
Researchers at the University of Connecticut's Department of Biomedical Engineering are working to develop a new, low-cost, CRISPR-based diagnostic platform to detect infectious diseases, including the novel coronavirus (SARS-CoV-2). Associate Professor Changchun Liu developed the "All-In-One-Dual CRISPR-Cas12a" (AIOD-CRISPR) method to enable simple, rapid, ultrasensitive, visual detection of SARS-CoV-2 and HIV viruses, intended for use at home or in small clinics.

Scientists Optimize Prime Editing for Rice and Wheat |
|
David R. Liu and his colleagues at Harvard University have developed prime editing, a new genome editing approach, which uses engineered Cas9 nickase (H840A)-reverse transcriptase (RT) fusion proteins paired with a prime editing guide RNA (pegRNA). Prof. Gao Caixia and his team at the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences reported the optimization of a prime editing system (PPE system) for creating desired point mutations, insertions, and deletions in two major cereal crops, rice, and wheat. The main components of a PPE system are a Cas9 nickase-RT fusion protein and a pegRNA.
