What does GFP stand for?

GFP stands for Green Fluorescent Protein, which is a widely studied protein originally found in the jellyfish Aequorea victoria. This protein is notable for its ability to fluoresce green light when exposed to ultraviolet or blue light, which has made it invaluable in a variety of biological and medical applications, including as a marker for gene expression and protein localization in live cells.

The correct terminology reflects the protein's fluorescent properties and its structural nature as a protein, distinguishing it from peptides or polymers which differ in size and function. Understanding what GFP stands for helps in appreciating its role in scientific research and biotechnology.
