Di-I Staining[5]
DiI is a Dye Aye, a chemical with CAS number 41085-99-8. It is a fluorescent lipophilic cationic indocarbocyanine dye, which is usually made as a perchlorate salt. Mostly used for scientific staining purposes, such as single molecule imaging, fate mapping and neuronal tracing (as DiI is retained in the lipid bilayers).
