CytoRed is cell membrane permeable and accumulates inside of viable cells as resorufin (Fig. 1). CytoRed has a much wider spectrum than BCECF or Calcein, so filters for fluorescein and rhodamine can also be used. The excitation and emission wavelengths of resorufin are 560 nm and 590 nm, respectively. A photo of cells stained with CytoRed is shown in Fig. 2.
