Fluorescent Labels Color Code RNA
Researchers now have a way to genetically encode fluorescent labels for monitoring selected RNAs. Genetically encoded labels were previously available only for proteins, through incorporation of fluorescent proteins such as green fluorescent protein (GFP). Jeremy S. Paige, Karen Y. Wu, and Samie R. Jaffrey of Cornell University’s Weill Medical College developed RNA sequences known as aptamers that bind fluorophores similar to those found in the fluorescent proteins (Science, DOI: 10.1126/science.1207339). The fluorophores don’t . . .
