4-Di-2-ASP（Cat No.:R071746）is a lipophilic fluorescent dye widely used in membrane potential studies, neuronal imaging, and cellular tracking. As a cationic amphiphilic probe, it selectively incorporates into biological membranes, making it ideal for real-time visualization of membrane dynamics, synaptic activity, and intracellular transport. This dye is particularly useful in neuroscience, electrophysiology, and live-cell imaging, where it helps study axonal transport, mitochondrial function, and neuronal connectivity. Its strong fluorescence properties make it valuable for tracking cellular processes and understanding membrane-associated mechanisms in biomedical and biochemical research.
