The LDL-C assay kit is intended for the direct quantitative measurement of low density lipoprotein cholesterol in human serum.

Testing Principle

During the assay, polyanions are absorbed on low density lipoprotein cholesterol(LDL-C) particles. In the meanwhile, the very low-density lipoprotein(VLDL) and high density lipoprotein (HDL) can be dissociated, generating cholesterol molecules. Cholesterol enzymes in the reagent can react with these cholesterol molecules, and the hydrogen peroxide generated in the reaction will be consumed due to the lack of coupling reagent. After the addition of specific surfactants, cholesterol molecules in LDL are released and then react with 4-AAP, CE, COD and POD. The reaction, also called Trinder reaction, generates purple chelate, and the color saturation of chelate is proportional to the concentration of LDL-C. The LDL-C level in samples can be calculated by comparing the results with that of the standard, which is prepared in the same way.
