General description

3,3′-Diethyloxadicarbocyanine iodide, also known as DODCI is a laser dye that belongs to the group of cyanine dyes.

Application

3,3′-Diethyloxadicarbocyanine iodide is a suitable dye for mode-locking both pulsed and cw tunable rhodamine 6G lasers. It has been used as a micellar probe as it is positively charged and it stays at the micelle–water interface.

The coenzyme quinone (CoQ) binding region of mitochondrial NADH:CoQ reductase (complex-I) was investigated by the fluorescent probes erythrosine-5'-iodoacetamide (ER) and 3,3'-diethyloxadicarbocyanine iodide (DODCI). Both steady-state and time-resolved fluorescence was used in these experiments. Both probes competed for the binding site

Uptake of alpha-aminoisobutyric acid (AIB) was examined in Ehrlich ascites tumor cells treated with the cation-exchange ionophore nigericin (20 microgram/ml). Membrane voltages were measured using the voltage-sensitive dye diethyloxadicarbocyanine (DOCC). In normal phosphate-buffered media, nigericin changed the distribution ratios of
