Rhodamine 123

Supplier: MARKER GENE TECHNOLOGIES MS

Cell-permeant, green fluorescent dye that can be used to monitor membrane polarization.

  • Accumulates in membranes
  • Measures membrane polarization
  • High luminescence quantum yield

Rhodamine 123 has found extensive use in biotechnology applications such as fluorescence microscopy, flow cytometry, fluorescence correlation spectroscopy and ELISA. Rhodamine fluorescence can be used as a measure of membrane polarization in live cell assays both within mitochondria and in bacteria, since it accumulates in membranes in a manner which is dependent on membrane polarization. R123 has also found use as a tracer dye in water to determine the rate and direction of flow and transport since it can be detected easily and inexpensively at very low levels using a fluorometer.

Formula: C₂₁H₁₉ClN₂O₄
MW: 398,843 g/mol
