Electron-microscopic evidence for particles smaller than 250 A in very low density lipoproteins of human plasma

Particle size distributions of very low density lipoproteins (VLDL) in man were examined by electron microscopy. A comparison was made between normolipidemic and hyperlipidemic subjects. The results showed that the VLDL fraction frequently contained particles between 100--250 A in diameter and in some cases particles less than 100 A were observed.
