Abstract
We determined the effects of different dialysis conditions on the antioxidant content,
duration of the lag phase and oxidation rate of LDL. Dialysis for 22 h resulted in
a 56%–66% reduction in the concentrations of β-carotene, lycopene and α-tocopherol.
The lag phase of copper-induced oxidation of freshly isolated LDL was considerably
longer than that of LDL dialysed for 22 or 44 h. Our data show that dialysis may result
in LDL preparations with antioxidant compositions that are not truly representative
of freshly isolated lipoproteins.
