Mammalian Expression of Infrared Fluorescent Proteins Engineered from a Bacterial Phytochrome

Infrared Vision Proteins from jellyfish and corals that fluoresce in the visible wavelength range have revolutionized optical imaging of cells. However, these wavelengths are absorbed by hemoglobin, water, and lipids and the proteins are thus not appropriate for deep-tissue imaging. Now Shu et al. (... View More
