Cholesterol is an important compound used in the structure of cell membranes, hormones, and cell signaling. Cholesterol is transported through the bloodstream within lipoproteins, which have cell-specific signals that direct the lipids they transport to certain tissues. Cholesterol exists within lipoproteins as both a free alcohol and a cholesteryl ester, which is the predominant form of cholesterol transport and storage.
High levels of cholesterol and cholesteryl esters have been associated with cardiovascular disease, and low levels of cholesterol may be associated with cancer, depression, or respiratory diseases.
We offer a variety of assays to measure cholesterol in various forms:
- Our Total Cholesterol Assays measure the total amount of free cholesterol plus cholesteryl esters in a convenient 96-well plate format.
- Our HDL-Cholesterol Assay specifically measures cholesterol associated only with high density lipoproteins.
- Our HDL and LDL/VLDL Cholesterol Assay allows you to separately and independently measure cholesterol levels associated with each fraction.
- Our Oxidized LDL ELISA Kits provide a convenient way to measuer OxLDL by way of three separate markers of oxidation.
