title: Lipid analysis and fatty acid profiles of individual arterial atherosclerotic plaques.
abstract: A protocol for the analysis of the lipid profile of microsamples of aortic tissue was developed. Lipid extraction was from intact tissue using acetone and chloroform/methanol (2/1, v/v). The extract was analyzed for total lipid, esterified cholesterol, cholesterol, triacylglycerol, and phospholipid. The extract was then processed to separate cholesteryl esters, triacylglycerol, and phospholipid which were hydrolyzed and the fatty acid composition was determined by GLC of pentafluorobenzyl ester derivatives. A lipid profile could be obtained on samples with a wet weight of 5 mg.
