GENERAL INFORMATION：
DPPE-NANOGOLD® consists of the 1.4 nm NANOGOLD® particle covalently linked to a single molecule of dipalmitoyl phosphatidyl ethanolamine. Conjugation is via the amine group on the ethanolamine head of the molecule. It is intended as a lipid label for use with micelles and other dual-phase systems1,2 in the same manner as the previously described undecatungstate membrane label3 . It has been used to prepare gold-decorated liposomes1 , and also to track the dellivery of a liposomally encapsulated antifungal drug2 . Its structure is shwon in figure 1:
Heavily gold-labeled liposomes may be formed by dissolving the Nanogold®-DPPE in chloroform, mixing with water, evaporating the chloroform, then using sonication or other usual preparative methods to form vesicles1 . Nanogold®-DPPE may also be diluted with unlabeled DPPE or with other lipids and used to prepare less heavily labeled liposomes. Incorporation of 0.1 to 1 % Nanogold®-DPPE with an unlabeled lipid is usually appropriate for preparing Nanogold®-labeled liposomes with the same properties and morphology as those prepared without the gold label2 . Once incorporated into micelles or other structures, it may be used according to the procedures required by individual experiments in the same manner as unlabeled DPPE
GENERAL INFORMATION：
Palmitoyl-NANOGOLD® consists of the 1.4 nm NANOGOLD® particle covalently linked to a single palmitoyl molecule. Conjugation is via an amide linkage to the carboxylic group at the head of the molecule. It is intended as a lipid label for use with micelles and other dual-phase systems1 in a similar manner to the previously described undecatungstate membrane label2 . Its structure is shwon in figure
