Acoustic Reporter Genes 2.0

The first generation of acoustic reporter genes provided a key proof of concept but were insensitive, burdensome and impossible to image continuously. Welcome ARG 2.0! These new reporter genes provide much greater sensitivity, nonlinear ultrasound contrast, and ease-of-use for expression in a variety of cell types. Congrats to Rob, Marjorie, Tom and colleagues on this major advance! Constructs for mammalian cells and bacteria available on Addgene.
