Fluorescent Proteins

Fluorescent proteins are naturally occurring proteins that can emit bright colors when exposed to specific wavelengths of light. Initially discovered in jellyfish, they have become valuable tools in science, particularly in biology. Researchers use these proteins to tag and visualize cells, proteins, or other biological structures under a microscope. By incorporating fluorescent proteins into experiments, scientists can track processes in living organisms, observe cellular interactions, and study genetics in real-time. Their versatility and ability to illuminate biological functions help advance our understanding of various life processes.
