ffn 270 hydrochloride

FFN270 hydrochloride, a fluorescent tracer for norepinephrine and vesicular monoamine transporters, features dual resolved absorption/excitation peaks that vary with solvent pH (FFN270 ex: 320 nm or 365 nm, em: 475 nm). It serves as a ratiometric fluorescent pH-sensor, highlighting its utility in monitoring norepinephrine.
