This fluorescent biotin derivative is a useful tracer for studying neuronal morphology. The biotin portion of the molecule allows researchers to amplify the fluorescent signal using standard biotin-avidin or biotin-streptavidin biochemistry. The staining can tolerate aldehyde fixation, sectioning, and washing with detergent.    &lamba;Abs/&lamba;Ems 428/532 nm  Yellow solid soluble in water  Store desiccated at ‰¤4°C and protect from light  C33H42K2N6O11S3
