Green to Red with Blue Light: Russian Scientists Uncover Fluorescent Protein s Unexpected Trick | GenomeWeb

Researchers from the Russian Academy of Sciences and Russian biotech firm Evrogen have developed a fluorescent protein that can change its emission from green to red following activation with blue light, the first known fluorescent protein to display such properties.

The discovery is notable because it may allow researchers to conduct so-called pulse-chase experiments to track the movement of organelles and proteins over longer periods in living cells due to the minimal toxicity effects of blue light on living organisms.
