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.

A cylindrical cam device includes an axle and a plurality of disk portions disposed about the axle. The plurality of disk portions define a plurality of interstitial regions disposed between the plurality of disk portions. Each of the plurality of disk portions comprises a radial edge. The radial edge of each of the plurality of disk portions comprises a material or structure capable of retaining a liquid and releasing at least a portion of the liquid onto a substrate. A method for facilitating electrophoretic analysis of biological samples utilizing the cylindrical cam device is also disclosed.

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.

The invention relates to, among other things, a method for performing electrophoresis with in-situ calibration. The method includes combining a volume of a test sample with a volume or quantity of a calibrating sample to form a final volume, where the volume of the calibrating sample includes a known concentration of a calibrator and the final volume includes a known ratio of test sample to calibrating sample. The method also includes depositing a loading fraction in a receiving well of an electrophoretic gel, in which the loading fraction is a fraction of the final volume, and separating the loading fraction along a common separation lane of the electrophoretic gel such that components of the test sample and the calibrator are separated from one another along the common separation lane. The method also includes detecting the calibrator and separated components of the test sample within the common separation lane and measuring the level of the calibrator and separated components of the test sample based on the detecting, thereby performing electrophoresis with in-situ calibration.
