title: Isolation and partial characterization of a guinea pig serum apolipoprotein comigrating with apo-E on sodium dodecyl sulfate-polyacrylamide electropherograms.
abstract: Study of guinea pig plasma lipoproteins has shown that they contain a polypeptide that comigrates with the arginine-rich polypeptide (apo-E) by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. This comigrating polypeptide differs from apo-E in its amino acid composition, immunological cross-reactivities, electrophoretic mobility in urea polyacrylamide gel, and elution volume from Sephadex gel columns. It is present in very low density lipoproteins and low density lipoproteins from both control and cholesterol-fed guinea pigs.
