FM1-84（Cat No.:R072065）is a lipophilic fluorescent dye commonly used in neuroscience research to label and track neuronal activity. It is particularly useful for visualizing neuronal membrane dynamics and synaptic vesicle trafficking. FM1-84 is known to stain live cells, binding to the plasma membrane and being incorporated into endocytic vesicles during synaptic vesicle recycling. This allows researchers to study membrane processes in living neurons in real-time. It is widely employed in studies of synaptic function, neurodegenerative diseases, and neuronal signaling, offering valuable insights into cellular communication and brain function.
