Figure 4. Analysis of plasma apolipoprotein content.

An aliquot of lipoproteins isolated by sequential density ultracentrifugation from equal amount (400 μl) of pooled plasma from 5 mice were loaded onto reducing 4 – 16 % SDS polyacrylamide gel and stained with Coomassie blue. Proteins were identified with respect to the migration of molecular weight standards. W, wild type mice; T, SR-BI transgenic mice.
