The present work describes a procedure for determining apolipoproteins (apo) B-100 and B-48 in subfractions of triglyceride-rich lipoproteins by analytical sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) with Coomassie staining. The chromogenicity of the two apoB species was found to be almost equal, and independent of lipoprotein particle size. Both proteins were sensitive...
