C-terminal HIS-tagged full-length Green Fluorescent Protein, expressed in E. coli. Green fluorescent protein (GFP) is a cytoplasmic protein found in jellyfish Aequorea victoria (1).

GFP acts as an energy transfer receptor and is actively involved in the transduction of blue chemiluminescence produced by the protein aequorin. Its main function is to convert this chemical energy into green fluorescence through an efficient energy transfer process. GFP, Aequorea victoria (His) is the recombinant protein, expressed in E. coli. and has molecular weight of 27 kDa.
