DiOC16(3) is a lipophilic cyanine dye with two C16 hydrocarbon chains. It can be optimally excited by the 488 nm argon laser line with green fluorescence emission (&lamda;Ex/&lamba;Em = 484/501 nm). The dye can be used to stain cytoplasmic membranes. Recently, DiOC16 has been combined with DPA to detect cell membrane potential change with high sensitivity. Please also see the DiO/DPA Membrane Potential Detection Kit (30037)).    Orange solid soluble in DMF and DMSO at >5mg/mL  &lamba;Abs/&lamba;Em (MeOH) = 484/501 nm  ε = ~130,000  Store at 4°C and protect from light  C55H88N2O9  MWt: 921.30  [ 161433-32-1]
