  • Method of determining the amount of cholesterol in a high-density lipoprotein
    Patent number: 5888755
    Abstract: Provided is a method of determining the amount of cholesterol in high-density lipoprotein (HDL), which comprises reacting an HDL-containing sample with cholesterol esterase and cholesterol oxidase or cholesterol dehydrogenase in the presence of a reagent for aggregating lipoproteins- except HDL, and determining the amount of hydrogen peroxide or reductive co-enzyme formed therein.
    Type: Grant
    Filed: November 10, 1997
    Date of Patent: March 30, 1999

  • Method for determination of cholesterol in low-density lipoprotein or very low-density lipoprotein
    Patent number: 5888827
    Abstract: Cholesterol in low-density lipoprotein (LDL) or very low-density lipoprotein (VLVL) in a sample is determined in the presence of a sugar compound and/or a protein-solubilizing agent.
    Type: Grant

  • Method of determining the amount of cholesterol in a high-density lipoprotein
    Patent number: 5736406
    Abstract: Provided are a method of determining the amount of cholesterol in high-density lipoprotein (HDL), which comprises measuring the amount of cholesterol in low-density lipoprotein (LDL), very-low-density lipoprotein (VLDL) and chylomicron (CM) in a sample in the presence of a sugar compound and/or a protein solubilizing agent, and calculating the difference between the amount of cholesterol in LDL, VLDL and CM and the total amount of cholesterol in the sample, and a method of determining the amount of cholesterol in HDL, which comprises measuring the amount of cholesterol in HDL in a sample in the presence of a sugar compound and/or a protein solubilizing agent.
