Patent ID: 8148096

Claim:
A method for preparing microtitration plates comprising wells coated with a lipid substrate onto which α-eleostearate groups are bound covalently, said method comprising the steps of: adding to the wells of said plates said lipid substrate onto which α-eleostearate groups are bound covalently, said lipid substrate being in solution in a solvent; and evaporating under vacuum said solvent until a coating of said lipid substrate having a thickness of approximately 0.5 to approximately 5 μm is formed on the walls of the wells of the microtitration plates, wherein said lipid substrate is selected from the group consisting of: (i) purified triglycerides of tung oil of general formula where R 1 and R 3 represent identical or different fatty acid residues comprising 12 to 20 carbon atoms, and said fatty acid residues optionally having one or more unsaturations, and where R 2 represents α-eleostearic acid, (ii) lipids containing 1 or 2 α-eleostearate chains in a position that provides regioselectivity of a lipase or a phospholipase, said lipids selected from the group consisting of diglycerides, monoglycerides, cholesterol esters and phospholipids, (iii) citronellol α-eleostearate of the following formula: (iv) acid esters of α-eleostearate with molecules selected from the group consisting of propanolol, sotalol, carvedilol, and menthol.
