Fluorescent Neuronal Tracers
Fast Blue (FB), Diamidino Yellow (DY), True Blue (TB) and Granular Blue (GB) are fluorescent dyes most commonly used as retrograde neuronal tracers.
FB is the tracer of choice for retrograde motoneuronal labeling in long-term experiments. FB can be used alone or with other types of fluorescent tracer dyes to map neuronal pathways.
When combined with FB, TB, or GB, DY is effective in double-label experiments aimed at demonstrating the existence of divergent axon collaterals.
