Green Fluorescent Protein, or GFP, was first isolated from the crystal jellyfish Aequorea victoria in the 1960s. In 1994, GFP was successfully cloned<cite>Chalfie1994</cite>, allowing researchers to use the protein as a screenable marker for the first time. Virtually harmless in live cells, GFP has the unique pheotype of glowing bright green under ultraviolet light. GFP functions entirely of its own accord, and requires no exogenous material besides ionizing radiation in order to fluoresce. This allows GFP to be used as a marker accompanying transfected DNA, and has been used extensively in academia. | Green Fluorescent Protein, or GFP, was first isolated from the crystal jellyfish Aequorea victoria in the 1960s.

As the mice tumors proliferated, so did GFP. This allowed for easy differentiate between tumors and stroma cells, greatly aiding cancer researchers. | ||
