CellTracker CM-DiI (CM-DiI) is a lipophilic fluorochrome designed for tracking lymphocyte migration. It effectively detects labeled cells in histological sections (excitation 553 nm; emission 570 nm) [1] [2].

DiI triflate is one of lipophilic fluorescent stains for labeling membranes and other hydrophobic structures. The fluorescence of these environment-sensitive dyes is greatly enhanced when incorporated into membranes or bound to lipophilic biomolecules such as proteins although they are weakly fluorescent in water.

DiI (DiIC18(3)) is a lipophilic membrane dye commonly used as a long-term tracer for neurons and other cells. DiI fluoresces very weakly before it enters the cell membrane, and only after it enters the cell membrane can it be excited to emit a strong orange-red fluorescence (λex=549 nm, λem=565 nm).

DiI iodide1 is one of lipophilic fluorescent stains for labeling membranes and other hydrophobic structures. The fluorescence of these environment-sensitive dyes is greatly enhanced when incorporated into membranes or bound to lipophilic biomolecules such as proteins although they are weakly fluorescent in water.

Diiodofluorescein disodium salt [another name: erythrosin B [(85%)], C20H8I2Na2O5, and [CAS No 16423-68-0] is a widely used dye in cosmetic and food products.

2,6-Diiodo-BODIPY 493/503, a fluorescent F-Bodipy dye, features a diiodo substitution at the (pyrrole) 2,6 position. This pyrrole iodine substituent imparts a red hue to the compound [1].

3,4,9,10-Perylenetetracarboxylic-diimide (PTCDI), a dimethylimine and organic heteropolycyclic compound, finds application in biological dyes and indicators [1].

5(6)-Carboxyfluorescein diisobutyrate, a protected form of 5(6)-carboxyfluorescein, serves as a fluorescence pH indicator [1].

DiIC16(3), a long-chain carbocyanine dye, is extensively utilized for labeling cells, organelles, liposomes, viruses, and lipoproteins [2].

Sudan III (Solvent Red 23) is a solvent dye used to color nonpolar substances.

Sudan II (Solvent Orange 7) is a dyes.
