LIPID SYNTHESIS, INTRACELLULAR TRANSPORT, AND STORAGE : III. Electron Microscopic Radioautographic Study of the Rat Heart Perfused with Tritiated Oleic Acid.

Abstract

Rat hearts pulse-labeled by perfusion in vitro with 9,10-oleic acid-(3)H for 15 or 30 sec were shown to take up the fatty acid extensively. In hearts postperfused with unlabeled medium for 15 sec or more, 90% of the radioactivity was recovered in esterified lipids. The radioautographic reaction was localized initially over elements of the sarcoplasmic… (More)
