Usual purification procedures of LDL and Lp(a) require numerous, extensive and prolonged sample handlings: this greatly increases the possibility of spontaneous oxidation. We have developed a method which, making use of two short-run ultracentrifugations in vertical rotors alternated by two rapid column-chromatography steps (SRUC), significantly shortens the preparation time to 3.5 h (LDL) and does not demand additional instrumentation or particular accuracy. Purification of Lp(a) requires a further wheat germ agglutinin chromatographic step, which can be accomplished within 30 min. More importantly, the method significantly reduces spontaneous oxidation as compared with classical isolation procedures. LDL isolated by the standard sequential method exhibits more extensive apolipoprotein B100 degradation, lipid peroxidation, and endogenous antioxidant (vitamin E) loss than the same lipoproteins obtained by means of the SRUC. This procedure may have be particularly valuable in experiments evaluating the effects of oxygen radical-induced modifications, especially in vitro.
