[The application of lipoprint-system for analysis of sub-fractional spectrum of lipoproteins of blood serum.]
2016
: The lipoproteins of low and high density are presented by heterogeneous specter of particles differing by size, density, charge, composition and functional characteristics. The prevalence of small dense particles of lipoproteins of low and high density in blood plasma is associated with higher risk of development of coronary heart disease. The identification of subfractional spectrum of lipoproteins in clinical purposes is complicated because of requirement of expensive equipment and reagents and extended time of implementation. The lipoprint-system (Quantimetrix Lipoprint LDL/HDL System, USA) based on the vertical electrophoresis using 3% polyacrilamid gel, permits shortening time of sub-fractioning of lipoproteins up to three hours. In the spectrum of apoB-containing lipoproteins of very low density, intermediate density, C, B, A, lipoproteins of low density 1 and 2, small dense (lipoproteins of low density 3-7) are singled out. In the spectrum of lipoproteins of high density up to 10 sub-fractions associated in three groups and represented by large (lipoproteins of high density 1-3), intermediate (lipoproteins of high density 4-7) and small (lipoproteins of high density 8-10) particles are singled out. The article describes technique of identification of spectrum of particles of lipoproteins of low and high density in human blood serum. The conditions of implementation of experiments are presented. The advantages and limitations of technique are indicated. The number of examples of application of indices of sub-fractional spectrum of lipoproteins as additional markers of evaluation of aterogenity of lipid profile are presented. The conclusion is made concerning possibility of application of technique in clinical laboratory diagnostic.
