HCID 50522795,7-DOCOSADIYNOIC ACID

Procedure

Ganglioside GM1, cholera toxin from Vibrio Cholerae, human serum albumin, and wheat germ agglutinin were purchased from Sigma. 5,7-docosadiynoic acid was synthesized. Deionized water was obtained by passing distilled water through a Millipore μF ultrapurification train. Solvents used were reagent grade. The ganglioside GM1 was mixed at 5 mol % with the diacetylene “matrix lipid” monomers. Liposomes were prepared using the probe sonication method and polymerized by UV irradiation (254 nm). The conjugated ene-yne backbone of polydiacetylene liposomes results in the appearance of a deep blue/purple solution The visible absorption spectrum of the freshly prepared purple liposomes is shown in FIG. 25.
