Interactions of Lipoproteins with a Polyurethane and a PEO-Modified Polyurethane (PEO-Modified Surface is Resistant to Proteins but not to Lipoproteins)

摘要

Apo AI, AII, and B adsorbed extensively to the polyurethane surface, but not to the PEO-containing surface. In contrast the lipoproteins HDL, LDL, and VLDL adsorbed to the PEO surface as well as to the PU, suggesting that PEO is not resistant to the adsorption of lipoproteins, thus raising questions about its effectiveness as an antifouling agent on blood contacting surfaces.
