3H-Indolium, 2-[2-(4-hydroxy-3,5-diiodophenyl)ethenyl]-3,3-dimethyl-1-(3-sulfopropyl)-, inner salt CAS:145876-11-5

Tracing neuronal pathways: DiI can be used to trace the connections between neurons in the brain or other tissues. It is frequently used to label individual cells or small groups of cells and track their projections through their long axonal processes.

Cell membrane labeling: DiI is also useful for labeling the plasma membrane of cells. It can be incorporated into the lipid bilayer of cells, allowing researchers to track the movement and behavior of cells in live imaging experiments.

Lipid droplet staining: This compound has been employed to stain and visualize lipid droplets in cells or tissues. By selectively targeting and labeling these droplets, researchers can investigate lipid metabolism and related processes.

Imaging of cellular structures: DiI can also be used to stain various cellular structures, such as mitochondria, endoplasmic reticulum, and Golgi apparatus. By incorporating DiI into specific cellular compartments, researchers can gain insights into their dynamics and interactions.
