OptiPrep™ Reference List RM01
Analysis of plasma lipoproteins
- This OptiPrep™ Reference List contains a brief summary of the methodology for the isolation and analysis of these particles (Section 1); the main aim of this Reference List however is to provide, in Section 2, a comprehensive list of references that report the use of OptiPrep™ for the fractionation of VLDL, LDL and HDL and also LDL and HDL sub-classes. The reference list (Section 1c) at the end of Section 1 applies only to this section.
1. Methodological review
1a. Separation and analysis of VLDL, LDL and HDL
Although ultracentrifugation is regarded as the “gold standard” method for the fractionation of plasma lipoproteins, the traditional method of sequential flotation by incrementally increasing the density of the plasma with KBr to provide sequentially VLDL, LDL and HDL is technically simple but excessively tedious (requiring approx. 3 days). The alternative approach involves the use of either discontinuous or continuous KBr/NaCl gradients; these gradients are technically very difficult to produce and handle. Detailed descriptions of the methodologies can be found in references 1-5. Moreover use of some add-on analytical techniques often necessitates removal of the salt by dialysis, adding up to 12 h to the procedure. Moreover, the use of high salt concentrations may cause the loss of certain surface apoproteins from lipoproteins.
The introduction of self-generated gradients of iodixanol in 1996 [6,7] solved many of the problems associated with earlier technology. A simple one step centrifugation for 3 h that resolves VLDL, LDL and HDL, avoiding the use of technically-difficult salt gradients is summarized in Figure 1. Chylomicron-free plasma is simply mixed with OptiPrep™, transferred to tube for a near-vertical rotor; overlayered with a little saline to fill the tube and centrifuged for 3 h. During the centrifugation the shallow resolving gradient is formed and the lipoproteins move to their banding density. The gradient may be collected as shown in Figure 1 by tube puncture or by aspiration from the meniscus.
1b. Separation and analysis of LDL subclasses
By a small modulation in the starting format, the gradient may be adapted to the fractionation of LDL subclasses; the plasma is adjusted to 12% (w/v) iodixanol (as recommended in refs 6 and 7) but it is overlayered by a solution of 9% (w/v) iodixanol. In a small volume near-vertical rotor such as the Beckman TLN100 the volumes of plasma/12% iodixanol and 9% iodixanol are equal [8]. In the larger volume NVT65 the volumes of 3 ml and 8 ml respectively allow a better resolution of the denser LDL from the HDL [9] and the low density region of the gradient is more shallow , allowing a greater linear separation of the LDL subclasses. In Figure 2 the (3ml + 8 ml) configuration is shown in conjunction with the use of a Coomassie blue stained plasma sample; this allows a density profile of the LDL band to be produced by scanning a digital photograph of the tube assessed without unloading the gradient or assaying the fractions for cholesterol and/or triacylglycerol.
- This strategy has been adapted to the analysis of HDL subclasses in a Sudan black stained plasma [10]
- Detailed protocols for the purification and analysis of the VLDL, LDL and HDL and for the analysis of LDL subclasses are contained in Application Sheets M07 and M08 respectively. The Application Sheets can be accessed from the “Macromolecules and Macromolecular Complex Index” section. Other OptiPrep™ Application Sheets on the preparation of self-generated gradients and harvesting of gradients may also be accessed from the top of the Index.

2. Bibliography
Section 2a lists references reporting studies on plasma lipoproteins and is subdivided alphabetically into animal species (e.g. 2a-1 Black bear). The majority of papers are concerned with human plasma lipoproteins (2a-5); this section is subdivided into those concerned with major HDL, LDL and VLDL classes (2a-5-1), HDL subclasses (2a-5-2) and LDL subclasses (2a-5-3). Within Sections 2a-5-1 and 2a-5-2, references are further divided according to research topic, listed alphabetically. A reference may appear in two or more of these research topic subsections. Section 2b lists references reporting the analysis of lipoproteins from sources other than plasma. Within all sections references are listed alphabetically according to first author and chronologically for multiple papers from the same first author.

1. Methodological summary
After protein has been incorporated into some form of liposome, it is usually necessary to resolve the newly formed proteoliposomes from any unincorporated protein. The most widely used strategy is described in Figure 1: the sample is adjusted to a density of 1.17-1.22 g/ml (depending on the OptiPrep™ diluent this is approx. equivalent to 30-40% w/v iodixanol) by mixing with a highdensity stock solution and layered beneath two lower density layers. The topmost layer is sometimes the isolation buffer rather than a low density iodixanol solution. During centrifugation the proteoliposomes float up through the 1.11-1.15 g/ml barrier to band at the top interface. The big advantage of this strategy is that the unincorporated protein remains in the sample zone and will even tend to sediment in the opposite direction. If the sample is layered on top of a density barrier the proteoliposomes and the free proteins sediment in the same direction. Depending on the details of the gradient and the centrifugation conditions, the separation may be based either on the difference in density between the proteins and proteoliposomes or the more rapid movement of the larger proteoliposomes.
There are some significant variants to this general strategy, for example the omission of a low-density layer entirely. The reported g-forces also vary quite widely, most are in the 200-300,000 g range but both higher 500,000 g for 1 h and lower 150,000 g for 18 h have been reported. Some of the variations in methodology are listed in the Table in Section 2.

The entries are listed alphabetically according to principal area of investigation. All of the papers report the use of flotation rather than sedimentation for purifying the proteoliposomes (the table continues on the next page).
