C6 NBD sphingomyelin is a sphingomyelin derivative that is tagged with a fluorescent group C6 nitrobenzoxadiazole (C6 NBD). Sphingomyelin naturally exists in mammalian cell membranes, especially membranes of the myelin sheath. C6 NBD sphingomyelin has been used to study the metabolism and transport of sphingomyelins.
