when liposomes containing the fluorescent lipid 1,2- ( palmitoyl-n-4-nitrobenzo-2-oxa-1,3-diazole-amino-caproyl ) phosphatidylserine [ palmitoyl-c6-nbd ) -ps ) , were incubated with monolayer cell cultures at 2 degrees c , spontaneous transfer of the fluorescent lipid from the liposomes to the cells occurred , resulting in prominent labeling of the plasma membrane .
