    摘要: It is intended to provide an assay method whereby the activity of a lipid-modifying enzyme can be conveniently measured over a wide range and a drug capable of controlling a lipid-modifying enzyme with the use of this assay method. The above problem can be solved by, for example, a method of measuring the activity of a lipid-modifying enzyme which comprises the steps of (I) preparing a lipid micelle containing a biotinylated lipid and a substrate for the lipid-modifying enzyme; (II) bringing the lipid micelle prepared in the above step (I) into contact with the lipid-modifying enzyme; and (III) evaluating the activity of the lipid-modifying enzyme by applying an evaluation method using the proximity effect to the product obtained in the above step (II).

    摘要: An LDL cholesterol measurement method that can be used with a test piece is provided. The LDL cholesterol measurement method for measuring LDL cholesterol in a sample has (A) a step of providing a total-cholesterol measurement portion and a non-LDL cholesterol measurement portion for measuring non-LDL cholesterol, which is cholesterol other than LDL cholesterol; (B) a step of measuring the total cholesterol in the sample in the total-cholesterol measurement portion; (C) a step of measuring the non-LDL cholesterol in the sample in the non-LDL cholesterol measurement portion; and (D) a step of obtaining the LDL cholesterol level in the sample by subtracting the non-LDL cholesterol value measured in the step (C) from the total-cholesterol value measured in the step (B).

    摘要: A method of selectively assaying components (in particular, cholesterol) in very low-density lipoprotein (VLDL) which is one of serum lipoproteins. In this assay, an enzyme reaction of lipoprotein lipase (LPL) or cholesterol esterase (CE), which are enzymes reacting well with high-density lipoprotein (HDL) and VLDL, is carried out in the presence of calixalene or its salt optionally together with one or more substances selected from among albumin and basic amino acids.

    摘要: It is intended to provide a quantification method whereby cholesterol in remnant-like lipoproteins can be conveniently and highly sensitively quantified without resorting to a procedure of separating a sample and a reagent and a kit therefor. A method for quantifying remnant-like lipoprotein cholesterol in a sample characterized by comprising, in an aqueous medium containing the sample and in the presence of a combination of specific surfactants and an enzyme hydrolyzing a phospholipid, reacting the remnant-like lipoprotein cholesterol in the sample with cholesterol ester hydrolase and cholesterol oxidase or cholesterol dehydrogenase (coexisting with an oxidized coenzyme) and then quantifying the hydrogen peroxide or the reduced coenzyme thus formed.
