Figure 1. Green-to-red photoconversion of Dendra2-tagged proteins. HeLa cells were transiently transfected with vectors encoding Dendra2-tagged fusion proteins. Dendra2 was converted to the red state in selected cells by brief illumination with a 488 nm laser and imaged with a confocal microscope in the green and red channels.
