Abstract: The application describes methods for determining the particle number and/or molar mass of lipoprotein(a) subform(s) in a biological sample using enzyme linked immunosorbent assay (ELISA). The methods described herein significantly improve lipoprotein ELISA methods and devices capable of quantifying particle numbers and population mass of Lp(a) particles. This technology offers a method for the efficient and cost-effective measurement of specific Lp(a) in a rapid, low-cost format, rather than limited measurement of Lp(a) concentration in patient tissues. The ability to measure the particle number and/or molar mass of lipoprotein(a) subform(s) in a biological sample also provides a useful diagnostic tool for assessing cardiovascular risk in a subject.

Abstract: The application describes methods for determining the concentration and/or particle number of a lipoprotein(a) subform in a biological sample using capillary isotachophoresis laser induced fluorescence (CE-ITP-LIF) and compositional analysis of lipoprotein(a) particles. The ability to measure the concentration and/or particle number of a lipoprotein(a) subform in a biological sample provides a useful diagnostic tool for assessing cardiovascular risk in a subject.

Abstract: A method for determining the molar concentration of specific lipoprotein particles present in a bodily fluid is presented. Multipixel Capillary Isotachophoresis Laser Induced Fluorescence is applied to fluorescently-labeled lipoproteins or immunologically-labeled apolipoproteins, facilitating quantification of lipoproteins and/or lipid particles and/or their associated apolipoproteins in a sample. The measurements are used to predict the risks of developing, progressing in severity of diseases related to lipoprotein particles, including cardiovascular and metabolic disorders.

Abstract: This application describes a method for measuring the molar concentrations of lipoprotein particles and lipoprotein subclass particles in bodily fluid by Multipixel Capillary Isotachophoresis Laser Induced Fluorescence (MPCE-ITP-LIF) and compositional analysis of spherical lipoprotein particles. The ability to measure several kinds of lipoproteins and particles in one unified system provides a useful diagnostic tool for predicting the risk of developing metabolic diseases such as cardiovascular disease and cardiodiabetes.

Abstract: In one aspect, a method for determining the composition of individual Lp(a) subforms in a test sample is provided. The method involves providing a test sample comprising Lp(a) subforms obtained from a subject; separating the Lp(a) subforms in the test sample along an electrophoretic gel; measuring the migration velocity of the individual Lp(a) subforms along the electrophoretic gel; comparing, based on said measuring, the migration velocity of the individual Lp(a) subforms to a reference value; and determining, based on said comparing, the molar mass of the individual Lp(a) subforms. Methods for predicting cardiovascular health are also provided.
