Lucifer yellow CH is a fluorescent probe that contains a free hydrazido group that reacts with aliphatic aldehydes at room temperature.1 Lucifer yellow CH displays excitation/emission maxima of 430/540 nm, respectively. It has been used as a biological tracer to monitor the branching pattern and regeneration of neurons, gap junction detection and characterization, and selective ablation of cells following aldehyde fixation.1,2
