“Therefore,” says Shu, “they are potential candidates for engineering blue- or red-shifted infrared fluorescent proteins, which then may be used for multicolor imaging and as FRET donors or ...

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

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

At a minimum, a hand-held blue or ultraviolet light source and a high-quality color digital camera can be used to illuminate the blot and capture images of the fluorescent protein bands.
