Green Fluorescent Proteins from Jellyfish

Green fluorescent proteins are widely used in basic science experiments, but in clinical medicine they are limited because, as their environment becomes more acidic, they lose brightness and even disappear. This is particularly relevant to imaging a cancerous tumor’s acidic microenvironment. Scientists at Osaka University, however, have found a jellyfish GFP that is much more tolerant of acidity, retaining its brightness and stability. MORE
