DiIC12(3) perchlorate is primarily used as a fluorescent dye in biological and cellular research. It is particularly effective in labeling cell membranes due to its lipophilic properties, allowing it to integrate seamlessly into lipid bilayers. This makes it a valuable tool for studying membrane dynamics, fluidity, and organization in live cells. Additionally, it is utilized in fluorescence microscopy and flow cytometry to visualize and track cellular processes in real-time. Its stable fluorescence emission and compatibility with various imaging techniques make it a reliable choice for researchers investigating membrane-related phenomena.
