Dilinoleyl DiI (1,1'-dilinoleyl-3,3,3',3'-tetramethylindocarbocynanine perchlorate), also known as FAST DiI, has identical absorption and emission spectra as DiI . Due to its unsaturated hydrocarbon chains, dilinoleyl DiI has a much faster lateral diffusion rate in cell membranes than DiI . This property makes dilinoleyl DiI particularly useful for tracing neurons in tissues.
