fluorescent protein

Fluorescent proteins are natural proteins found in certain organisms, like jellyfish and coral, that emit bright colors when exposed to light, particularly ultraviolet light. They are widely used in scientific research as powerful tools to visualize and track biological processes in cells. By attaching them to other proteins, scientists can observe how cells behave, interact, and develop in real time, enhancing our understanding of various biological functions. This made fluorescent proteins, like Green Fluorescent Protein (GFP), essential in fields such as genetics, cell biology, and medicine.
