FFN 270

FFN 270 is a fluorescent false neurotransmitter that selectively labels noradrenergic neurons via NET and VMAT2. It enables real-time imaging of synaptic vesicle release in vivo and in vitro, making it a valuable tool for studying neurotransmission dynamics in neuroscience research. Its excitation maxima shift with pH, exhibiting peaks at 320 nm or 365 nm with emission at 475 nm.
