  • Method for determining the relative amounts of all cholesterol-containing lipoproteins in body fluids
    Patent number: 5385828
    Abstract: The invention refers to a method for determining the relative amounts of all cholesterol-containing lipoproteins in body fluids comprising electrophoretically separating the lipoproteins of an aliquot of body fluid on a thin layer carrier matrix, incubating the carrier matrix, containing the separated lipoproteins with cholesterol esterase and cholesterol dehydrogenase, forming a provable complex, and determining the relative amounts of the different lipoprotein classes2. The new method makes it possible to simultaneously determine HDL-, LDL-, VLDL- and LP (X)-cholesterol in body fluids with a high accuracy even at small concentrations. The thin layer matrices obtained electrophoretically, are very easy to handle and to record.
