Used extensively as a fluorescent dye in biological research, it is particularly valuable for labeling lipids and membranes in live-cell imaging. Its bright fluorescence and ability to incorporate into lipid bilayers make it ideal for studying membrane dynamics and lipid trafficking. Additionally, it is employed in fluorescence microscopy to visualize cellular structures and processes, aiding in the understanding of cell function and interactions. Its application extends to diagnostic assays, where it helps detect and analyze lipid-related disorders.
