Key Differences between Green Fluorescent Protein and Yellow Fluorescent Protein

Green Fluorescent Protein

Green Fluorescent Protein (GFP) is a naturally occurring protein extracted from the jellyfish Aequorea victoria. Widely used in molecular and cell biology, GFP emits green fluorescence when exposed to ultraviolet or blue light. Its popularity arises from its ability to act as a non-invasive, in vivo marker for gene expression and protein localization. Scientists utilize GFP by fusing it with target proteins or incorporating its genetic sequence into organisms. This fusion allows researchers to visualize and track the movements and activities of specific proteins in living cells, providing valuable insights into cellular processes. GFP has become a powerful tool for studying gene function, cellular dynamics, and the advancement of various biotechnological applications.
