DIR iodide(dark red fluorescence)

DiR[1,1-dioctadecyl-3,3,3,3-tetramethylindotricarbocyanine iodide] is a lipophilic, near infrared fluorescent cyanine dye. This dye is often used to label other lipid soluble biological structures and cell plasma membrane. The fluorescence intensity of these environmentally sensitive fluorescent dyes is very weak before they enter the cell membrane, and increases greatly when they combine with the cell membrane. It has the characteristics of high extinction coefficient, j-dependence and short lifetime of excited state. DiR [1,1-dioctadecyl-3,3,3,3-tetramethylindotricarbocyanine iodide]  has strong near-infrared light penetrating cells or tissues and low autofluorescence level in the near-infrared region, which makes it especially suitable for in vivo imaging or tracing experiments.
