Green fluorescent protein

Green fluorescent protein (GFP) is a naturally occurring protein found in certain jellyfish, which glows bright green when exposed to ultraviolet light. Scientists have harnessed this property for various applications, particularly in biological research. By attaching GFP to proteins in living organisms, researchers can visually track and study cellular processes in real time under the microscope. This technique has revolutionized fields like genetics and developmental biology, enabling scientists to observe how cells interact and behave, ultimately enhancing our understanding of life at the cellular level.
