Reaktionsschritte

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