Product Description

DiIC₁₈(7); 1,1′-dioctadecyl-3,3,3′,3′-tetramethylindotricarbocyanine iodide

DiR is a lipophilic, near-infrared fluorescent cyanine dye. The dye is useful for labeling cytoplasmic membrane. The two long 18-carbon chains insert into the cell membrane, resulting in specific and stable cell staining with no or minimal dye transfer between cells. A stock solution of the dye can be made in ethanol. Cell staining can be effected using the dye at 1-10 uM concentration and 10-20 min incubation time.

Please also see our other cytoplasmic membrane dyes. DiR, DiD, DiI and Neuro-DiO can be used in combination for multicolor imaging.
