Low-Density Lipoprotein Cholesterol (LDL-C) Colorimetric Assay Kit (Double Reagents) (E-BC-K205-S)
For research use only.
| Detection Principle | Lipoproteins (except low-density lipoprotein cholesterol (LDL)) such as high density lipoprotein (HDL), chylomicron (CM), and very low density lipoprotein (VLDL) change structure and dissociate under the action of surfactants. The released micronized cholesterol molecules react with cholesterol enzyme reagents, and the generated hydrogen peroxide is trapped in the absence of coupling agent. It is consumed without color development. At this time, the LDL particles are still intact, and then the reagent containing coupling agent is added, which can dissociate the LDL particles to release cholesterol, which is catalyzed by cholesterol esterase (CE) and cholesterol oxidase (CO) and produce hydrogen peroxide. Hydrogen peroxide is catalyzed by oxidase (POD) in the presence of 4-aminoantipyrine (4-AA) and phenol (T-OOS) to form a red quinone compound, the shade of color is directly proportional to the LDL-C content. |
