Pinacyanol iodide is a fluorescent cationic cyanine dye used to stain biological specimens. It is the obstetric diagnostic aid. The mechanism of tracing with pinacyanol iodide dyes is based on their lipid solubility. Pinacyanol iodide dyes are more efficacious than classical tracing methodologies especially during early stages of development and consequently have been used to reveal the spatiotemporal patterns of axonal development in different species. The unique properties of the pinacyanol iodide dye tracing method have opened up new avenues for tracing connections in human postmortem specimens. Pinacyanol iodide dye tracing is incompatible with alcohol fixation and paraffin embedding of tissue.
