  • Method for measuring triglyceride in low-density lipoprotein
    Patent number: 9360432
    Abstract: The present invention provides a method for a simple and accurate measurement of triglycerides in low-density lipoprotein in a sample comprising performing the following steps sequentially: (i) a step of generating free glycerol by allowing lipoprotein lipase to act on a sample, in an aqueous medium comprising the sample and a specific surfactant such as polyoxyethylene polyoxyalkylene polycyclic phenyl ether; (ii) a step of removing free glycerol present in the reaction solution of the above step (i); (iii) a step of generating free glycerol by allowing lipoprotein lipase to act on the reaction solution from which free glycerol has been removed in step (ii), in the presence of a specific surfactant such as polyoxyethylene polyoxyalkylene alkyl ether; and (iv) a step of measuring free glycerol generated in step (iii), and a kit used for the method.

  • Method for quantitating triglycerides in lipoproteins
    Publication number: 20050042703
    Abstract: The present invention relates to a method for conveniently quantitating TGs contained in various lipoproteins. A method for quantitating trigyceride (TG) in a particular lipoprotein which comprises eliminating free glycerol from a sample containing free glycerol and TG in the particular lipoprotein, then allowing the resulting sample to react with lipoprotein lipase and an enzyme system which generates hydrogen peroxide from free glycerol, and quantitating the generated hydrogen peroxide, is provided.
