16:0-12 Doxyl PC
16:0-12 Doxyl PC (1-Palmitoyl-2-stearoyl-(12-doxyl)-sn-glycero-3-phosphocholine) is a fluorescence quencher, and its nitrogen oxide is located downstream of the sn-2 chain. 16:0-12 Doxyl PC has a better fluorescence quenching effect onthe fluorophore is buried within the hydrocarbon interior of the bilayer.
