Green Fluorescent Protein (GFP)

Green fluorescent protein (GFP) is a unique protein originally found in jellyfish that glows bright green when exposed to ultraviolet or blue light. Scientists use GFP as a marker in various fields, particularly in biology, to visualize and track proteins and cellular processes in living organisms. By attaching GFP to other proteins, researchers can see where these proteins go and how they behave inside cells, enhancing our understanding of biological functions and diseases. Its ability to fluoresce makes it a valuable tool in research and biomedicine.
