C-terminal HIS-tagged full-length mCherry Fluorescent Protein, expressed in E. coli.
The mCherry protein is engineered from a fluorescent protein originally isolated from a coral and is widely used as a tracer in transfection and transgenic experiments. The prototype for these fluorescent proteins is Green Fluorescent Protein (GFP), which is a ~27 kDa protein isolated originally from the jellyfish Aequorea victoria. The mCherry protein is derived from dsRed, a red fluorescent protein related to GFP isolated from disc corals of the Discosoma genus.
