The pyrene and nitrobenzoxadiazole (NBD) labeled derivatives of the natural
sialyl Lewis(X) glycosphingolipid 1 were chemically synthesized as targets
for investigating microdomain formation in membranes. The fluorescent anal
ogs 2 and 3 were prepared by replacing the natural amide-linked fatty acid
with a fluorescent analog. (C) 2001 Elsevier Science Ltd. All rights reserv
