For a time, however, it appeared that fluorescent protein engineering had hit a 'yellow' wall in efforts to red-shift fluorescence emission. Fortuitously, this barrier had already been surmounted ...

Fluorescent proteins are also useful for tracking cell populations, such as tumor cells, in vivo. Thus far, the best tools for imaging in live, whole animals have been far-red fluorescent proteins ...

based BD Biosciences-Clontech is now offering academic and nonprofit researchers access to its collection of novel reef coral fluorescent proteins, which include AmCyan1 ... and yellow to three shades ...

Artificial cells using riboswitch-gene fusion in liposomes produce fluorescent proteins when detecting specific targets.

Glioblastoma stem cells with fluorescent labeling for prion protein (red), CD44 protein (green), and cell nucleus (blue) ...
