Chemical. CAS 905-96-4. Formula C21H19IN2S. Molecular Weight 460.31. 3,3-Diethyloxacarbocyanine iodide is a cyanine based dye that has been used for measuring membrane potentials in bacteria. The green fluorescent dye forms red fluorescent aggregates with increasing membrane potential. The spectral shifting phenomenon has been exploited to measure membrane potential and analyze bacterial viability by flow cytometry ratiometrically. Spectral data lambdamax 483nm methanol lambdaem 498nm methanol. The dye has also been used as laser dye and in photosensitization of mitochondria and endoplastic recticulum in animals and plant cells. It may be used as a conjugate for labelling cells for cytofluorometry studies and in the imaging of carbon nanotubesCNTs using fluorescence microscopy.
