Procedure

An estimated 30 nmol of the amino-derivatized 2-3 nm platinum cluster dissolved in 0.6 M triethylammonium bicarbonate in 20% isopropanol/water was evaporated to dryness five times from methanol, then dissolved in 3 mL of diclhoromethane, and treated with 200 nmol of palmitic anhydride. The mixture was stirred for one hour at room temperature, then washed three times with 0.1 M sodium phosphate buffer at pH 6.5. The remaining reaction mixture was evaporated to dryness, redissolved in 2:1 methanol/chloroform, then separated by gel filtration (GH25, Amicon eluted with 2:1 methanol:chloroform); the first species to elute is the dark brown palmitamido-platinum cluster. After evaporation to dryness, lipid conjugation was demonstrated by the extraction of the cluster into the chloroform layer when the palmitoyl cluster was shaken in a chloroform/water mixture with a small amount of methanol as a phase transfer agent.
