We speak to Dr. George Emanuel from Vizgen about their new MERSCOPE Platform and how it is accelerating the field of drug discovery by combining both single-cell and spatial genomics. A blocked blood vessel or the pressure of a tumor can lower oxygen levels in localized tissue without an observable difference in a pulse oximeter reading. The heart pumps it to the lungs, and the process begins again. Light is emitted from one side of the probe and travels through the tissue to the other side. In this interview, we speak to Svea Cheeseman at Refeyn about their SamuxMP products used for the analysis of adeno-associated viruses (AAV) capsids.
