Amplite(TM) Cholesterol Quantitation Kit

Cholesterol is required to build and maintain cell membranes. It modulates membrane fluidity over the range of physiological temperatures. Within cells, cholesterol is the precursor molecule in several biochemical pathways. Cholesterol is also an important precursor molecule for the synthesis of Vitamin D and the steroid hormones, including the adrenal gland hormones cortisol and aldosterone as well as the sex hormones progesterone, estrogens, together with testosterone and their derivatives. This Amplite(TM) Cholesterol Quantitation Assay Kit provides one of the most sensitive methods for quantifying cholesterol. The kit uses Amplite(TM) Red to quantify the concentration of cholesterol, which is related to the production of hydrogen peroxide in the cholesterol oxidase-mediated enzyme coupling reactions in the presence of cholesterol. The amount of cholesterol is proportional to the concentration of hydrogen peroxide formed in the enzyme coupling reaction cycle. In the presence of peroxidase, the fluorescence intensity of Amplite(TM) Red is proportional to the concentration of hydrogen peroxide that is converted to the concentration of cholesterol. The assay can be readily read with a fluorescence microplate reader at Ex/Em = 540/590 nm.
