Name one application of GFP in live-cell imaging.

Monitoring protein dynamics and cellular processes over time is a significant application of GFP in live-cell imaging. This capability arises from the intrinsic fluorescent properties of GFP, which allows researchers to tag specific proteins within living cells. By attaching GFP to proteins of interest, scientists can visualize and track these proteins in real-time as they move, interact, and change within the cellular environment. This dynamic observation contributes to a deeper understanding of various biological processes, such as protein localization, interaction networks, and cellular responses to stimuli. Such insights are crucial for studying cellular mechanisms and can facilitate advances in fields like developmental biology, cancer research, and neurobiology.
