NBD PS might be suitable as a component in premixed lipid solution for V-SNARE (N-ethylmaleimide-sensitive factor attachment protein receptor) proteo-liposomes preparation. It is also suitable for the preparation of control PS/PC (1-palmitoyl-2-oleoylsn-glycero-3-phospho-L-serine/1-palmitoyl-2-oleoyl-sn-glycero-phosphocholine) liposomes.
