summary: GFP permits the fluorescent tagging of proteins of interest which can be expressed in living organisms.
Green Fluorescent Protein(GFP)-Gene Construction
GFP is a protein found in Aequorea victoria, a bioluminescent jellyfish. In order to visualize your favorite protein you can attach this protein to your protein so that it will fluoresce. This is done by taking the DNA that encodes GFP and cloning it next to the gene that encodes your gene. This DNA is then added into your organism so that the organism makes the new fusion protein in the same way that it normally makes proteins.
