  • Product overview

    Abcam's HDL and LDL/VLDL Cholesterol Quantification Kit provides a simple quantification method of HDL and LDL/VLDL after a convenient separation of HDL from LDL and VLDL (very low-density lipoprotein) in serum samples. In the assay, cholesterol oxidase specifically recognizes free cholesterol and produces products which react with probe to generate color (570 nm) and fluorescence (Ex/Em = 538/587 nm). Cholesterol esterase hydrolizes cholesteryl ester into free cholesterol, therefore, cholesterol ester and free cholesterol can be detected separately in the presence and absence of cholesterol esterase in the reactions.

  • Notes

    Regulation of HDL (high-density-lipoprotein)-cholesterol and LDL (low-density-lipoprotein)-cholesterol plays a central role in various disease developments. It is well known that low levels of HDL and high level of LDL are associated with an increased risk of cardiovascular events.

Properties

  • RelevanceHDL (high-density-lipoprotein), LDL (low-density lipoprotein) and VLDL (very low-density lipoprotein) are lipoproteins that act as carrier proteins for cholesterol. The regulation of HDL-cholesterol and LDL-cholesterol plays a central role in various disease development. It is well known that low levels of HDL and high level of LDL are associated with an increased risk of cardiovascular events.

    • Measurement of total cholesterol, HDL, LDL/VLDL from serum samples. Total Cholesterol (blue), HDL (green), and LDL/VLDL (cream) cholesterol were measured following the kit protocol.
    • Wild type (WT) or farnesoid X receptor knock-out (FRX-KO) mice were treated with either vehicle (Veh) or a high fat-containing diet (HFD) for 16 weeks.

      Serum HDL (top) and LDL/VLDL cholesterol (bottom) from 5-7 mice/group was measured using ab65390 following protocol instructions. An asterisk (*) means P<0.05 between WT ad FXR-KO vehicle group. A pound (#) indicates P<0.05 between WT and FXR-KO HFD group.
