DiD, Lipophilic Tracer
This product is a carbocyanine-based, lipophilic fluorescent dye used to stably label cell membranes and lipid structures. It specifically integrates into lipid bilayers through its long alkyl chains and exhibits strong far-red fluorescence with excitation around 644 nm and emission near 665 nm. Its high photostability and low cytotoxicity make it an especially valuable tracer for long-term cell tracking, membrane dynamics, and in vivo imaging.
