WebNovember 2015. Therapeutic nucleic acids are powerful molecules for shutting down protein expression. However, their cellular uptake is poor and requires transport vectors, such as cationic polymers. Of these, poly (ethylenimine) (PEI) has been shown to be an efficient vehicle for nucleic acid transport into cells. WebHDL. Lipoproteins are a lipid + a protein (compound lipid). Because lipids are less dense than water, the density of lipoproteins decreases as the proportion of lipid to protein increases. Lipoproteins have a major role in lipid and cholesterol transport and metabolism. Lipoproteins are classified based on their density and composition.
